    Description: The crystal structure of a ternary protein complex has been determined at 2.4 angstrom resolution. The complex is composed of three electron transfer proteins from Paracoccus denitrificans, the quinoprotein methylamine dehydrogenase, the blue copper protein amicyanin, and the cytochrome c551i. The central region of the c551i is folded similarly to several small bacterial c-type cytochromes; there is a 45-residue extension at the amino terminus and a 25-residue extension at the carboxyl terminus. The methylamine dehydrogenase-amicyanin interface is largely hydrophobic, whereas the amicyanin-cytochrome interface is more polar, with several charged groups present on each surface. Analysis of the simplest electron transfer pathways between the redox partners points out the importance of other factors such as energetics in determining the electron transfer rates.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chen, L -- Durley, R C -- Mathews, F S -- Davidson, V L -- GM41574/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1994 Apr 1;264(5155):86-90.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biochemistry and Molecular Biophysics, Washington University School of Medicine, St. Louis, MO 63110.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8140419" target="_blank"〉PubMed〈/a〉

    Description: A diverse set of circadian clock mutants was isolated in a cyanobacterial strain that carries a bacterial luciferase reporter gene attached to a clock-controlled promoter. Among 150,000 clones of chemically mutagenized bioluminescent cells, 12 mutants were isolated that exhibit a broad spectrum of periods (between 16 and 60 hours), and 5 mutants were found that show a variety of unusual patterns, including arrhythmia. These mutations appear to be clock-specific. Moreover, it was demonstrated that in this cyanobacterium it is possible to clone mutant genes by complementation, which provides a means to genetically dissect the circadian mechanism.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kondo, T -- Tsinoremas, N F -- Golden, S S -- Johnson, C H -- Kutsuna, S -- Ishiura, M -- GM37040/GM/NIGMS NIH HHS/ -- MH43836/MH/NIMH NIH HHS/ -- New York, N.Y. -- Science. 1994 Nov 18;266(5188):1233-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉National Institute for Basic Biology, Okazaki, Japan.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7973706" target="_blank"〉PubMed〈/a〉

    Description: As a step toward developing poliovirus as a vaccine vector, poliovirus recombinants were constructed by fusing exogenous peptides (up to 400 amino acids) and an artificial cleavage site for viral protease 3Cpro to the amino terminus of the viral polyprotein. Viral replication proceeded normally. An extended polyprotein was produced in infected cells and proteolytically processed into the complete array of viral proteins plus the foreign peptide, which was excluded from mature virions. The recombinants retained exogenous sequences through successive rounds of replication in culture and in vivo. Infection of animals with recombinants elicited a humoral immune response to the foreign peptides.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Andino, R -- Silvera, D -- Suggett, S D -- Achacoso, P L -- Miller, C J -- Baltimore, D -- Feinberg, M B -- AI22346/AI/NIAID NIH HHS/ -- AI35545/AI/NIAID NIH HHS/ -- RR00169/RR/NCRR NIH HHS/ -- New York, N.Y. -- Science. 1994 Sep 2;265(5177):1448-51.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Microbiology and Immunology, University of California, San Francisco.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8073288" target="_blank"〉PubMed〈/a〉

    Description: In Drosophila and human cells, the TATA binding protein (TBP) of the transcription factor IID (TFIID) complex is tightly associated with multiple subunits termed TBP-associated factors (TAFs) that are essential for mediating regulation of RNA polymerase II transcription. The Drosophila TAFII150 has now been molecularly cloned and biochemically characterized. The deduced primary amino acid sequence of dTAFII150 reveals a striking similarity to the essential yeast gene, TSM-1. Furthermore, like dTAFII150, the TSM-1 protein is found associated with the TBP in vivo, thus identifying the first yeast homolog of a TAF associated with TFIID. Both the product of TSM-1 and dTAFII150 bind directly to TBP and dTAFII250, demonstrating a functional similarity between human and yeast TAFs. Surprisingly, DNA binding studies indicate that purified recombinant dTAFII150 binds specifically to DNA sequences overlapping the start site of transcription. The data demonstrate that at least one of the TAFs is a sequence-specific DNA binding protein and that dTAFII150 together with TBP are responsible for TFIID interactions with an extended region of the core promoter.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Verrijzer, C P -- Yokomori, K -- Chen, J L -- Tjian, R -- New York, N.Y. -- Science. 1994 May 13;264(5161):933-41.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute, University of California, Berkeley 94720-3202.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8178153" target="_blank"〉PubMed〈/a〉

    Description: Representational difference analysis was used to isolate unique sequences present in more than 90 percent of Kaposi's sarcoma (KS) tissues obtained from patients with acquired immunodeficiency syndrome (AIDS). These sequences were not present in tissue DNA from non-AIDS patients, but were present in 15 percent of non-KS tissue DNA samples from AIDS patients. The sequences are homologous to, but distinct from, capsid and tegument protein genes of the Gammaherpesvirinae, herpesvirus saimiri and Epstein-Barr virus. These KS-associated herpesvirus-like (KSHV) sequences appear to define a new human herpesvirus.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chang, Y -- Cesarman, E -- Pessin, M S -- Lee, F -- Culpepper, J -- Knowles, D M -- Moore, P S -- New York, N.Y. -- Science. 1994 Dec 16;266(5192):1865-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Pathology, College of Physicians and Surgeons, Columbia University, New York, NY 10032.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7997879" target="_blank"〉PubMed〈/a〉

    Description: The structure of the heterodimeric flavocytochrome c sulfide dehydrogenase from Chromatium vinosum was determined at a resolution of 2.53 angstroms. It contains a glutathione reductase-like flavin-binding subunit and a diheme cytochrome subunit. The diheme cytochrome folds as two domains, each resembling mitochondrial cytochrome c, and has an unusual interpropionic acid linkage joining the two heme groups in the interior of the subunit. The active site of the flavoprotein subunit contains a catalytically important disulfide bridge located above the pyrimidine portion of the flavin ring. A tryptophan, threonine, or tyrosine side chain may provide a partial conduit for electron transfer to one of the heme groups located 10 angstroms from the flavin.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chen, Z W -- Koh, M -- Van Driessche, G -- Van Beeumen, J J -- Bartsch, R G -- Meyer, T E -- Cusanovich, M A -- Mathews, F S -- GM-20530/GM/NIGMS NIH HHS/ -- GM-21277/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1994 Oct 21;266(5184):430-2.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biochemistry and Molecular Biophysics, Washington University School of Medicine, St. Louis, MO 63110.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7939681" target="_blank"〉PubMed〈/a〉

    Description: To facilitate molecular genetic analysis of vertebrate development, haploid genetics was used to construct a recombination map for the zebrafish Danio (Brachydanio) rerio. The map consists of 401 random amplified polymorphic DNAs (RAPDs) and 13 simple sequence repeats spaced at an average interval of 5.8 centimorgans. Strategies that exploit the advantages of haploid genetics and RAPD markers were developed that quickly mapped lethal and visible mutations and that placed cloned genes on the map. This map is useful for the position-based cloning of mutant genes, the characterization of chromosome rearrangements, and the investigation of evolution in vertebrate genomes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Postlethwait, J H -- Johnson, S L -- Midson, C N -- Talbot, W S -- Gates, M -- Ballinger, E W -- Africa, D -- Andrews, R -- Carl, T -- Eisen, J S -- 1RO1AI26734/AI/NIAID NIH HHS/ -- HD07470/HD/NICHD NIH HHS/ -- NS23915/NS/NINDS NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1994 Apr 29;264(5159):699-703.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institute of Neurosciences, University of Oregon, Eugene 97403.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8171321" target="_blank"〉PubMed〈/a〉

    Description: The structure of the leech protein decorsin, a potent 39-residue antagonist of glycoprotein IIb-IIIa and inhibitor of platelet aggregation, was determined by nuclear magnetic resonance. In contrast to other disintegrins, the Arg-Gly-Asp (RGD)-containing region of decorsin is well defined. The three-dimensional structure of decorsin is similar to that of hirudin, an anticoagulant leech protein that potently inhibits thrombin. Amino acid sequence comparisons suggest that ornatin, another glycoprotein IIb-IIIa antagonist, and antistasin, a potent Factor Xa inhibitor and anticoagulant found in leeches, share the same structural motif. Although decorsin, hirudin, and antistasin all affect the blood clotting process and appear similar in structure, their mechanisms of action and epitopes important for binding to their respective targets are distinct.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Krezel, A M -- Wagner, G -- Seymour-Ulmer, J -- Lazarus, R A -- New York, N.Y. -- Science. 1994 Jun 24;264(5167):1944-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biological Chemistry and Molecular Pharmacology, Harvard Medical School, Boston, MA 02115.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8009227" target="_blank"〉PubMed〈/a〉

    Description: Protein tyrosine phosphatases (PTPs) constitute a family of receptor-like and cytoplasmic signal transducing enzymes that catalyze the dephosphorylation of phosphotyrosine residues and are characterized by homologous catalytic domains. The crystal structure of a representative member of this family, the 37-kilodalton form (residues 1 to 321) of PTP1B, has been determined at 2.8 A resolution. The enzyme consists of a single domain with the catalytic site located at the base of a shallow cleft. The phosphate recognition site is created from a loop that is located at the amino-terminus of an alpha helix. This site is formed from an 11-residue sequence motif that is diagnostic of PTPs and the dual specificity phosphatases, and that contains the catalytically essential cysteine and arginine residues. The position of the invariant cysteine residue within the phosphate binding site is consistent with its role as a nucleophile in the catalytic reaction. The structure of PTP1B should serve as a model for other members of the PTP family and as a framework for understanding the mechanism of tyrosine dephosphorylation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Barford, D -- Flint, A J -- Tonks, N K -- CA53840/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1994 Mar 11;263(5152):1397-404.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉W.M.

    Description: A gene, reaper (rpr), that appears to play a central control function for the initiation of programmed cell death (apoptosis) in Drosophila was identified. Virtually all programmed cell death that normally occurs during Drosophila embryogenesis was blocked in embryos homozygous for a small deletion that includes the reaper gene. Mutant embryos contained many extra cells and failed to hatch, but many other aspects of development appeared quite normal. Deletions that include reaper also protected embryos from apoptosis caused by x-irradiation and developmental defects. However, high doses of x-rays induced some apoptosis in mutant embryos, and the resulting corpses were phagocytosed by macrophages. These data suggest that the basic cell death program is intact although it was not activated in mutant embryos. The DNA encompassed by the deletion was cloned and the reaper gene was identified on the basis of the ability of cloned DNA to restore apoptosis to cell death defective embryos in germ line transformation experiments. The reaper gene appears to encode a small peptide that shows no homology to known proteins, and reaper messenger RNA is expressed in cells destined to undergo apoptosis.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉White, K -- Grether, M E -- Abrams, J M -- Young, L -- Farrell, K -- Steller, H -- 5 F32 NS08536/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 1994 Apr 29;264(5159):677-83.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute, Department of Brain and Cognitive Sciences, Cambridge, MA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8171319" target="_blank"〉PubMed〈/a〉

    Description: The Drosophila decapentaplegic (dpp) gene encodes a transforming growth factor-beta (TGF-beta)-like protein that plays a key role in several aspects of development. Transduction of the DPP signal was investigated by cloning of serine-threonine kinase transmembrane receptors from Drosophila because this type of receptor is specific for the TGF-beta-like ligands. Here evidence is provided demonstrating that the Drosophila saxophone (sax) gene, a previously identified female sterile locus, encodes a TGF-beta-like type I receptor. Embryos from sax mothers and dpp embryos exhibit similar mutant phenotypes during early gastrulation, and these two loci exhibit genetic interactions, which suggest that they are utilized in the same pathway. These data suggest that sax encodes a receptor for dpp.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Xie, T -- Finelli, A L -- Padgett, R W -- New York, N.Y. -- Science. 1994 Mar 25;263(5154):1756-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Waksman Institute, Rutgers University, Piscataway, NJ 08855-0759.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8134837" target="_blank"〉PubMed〈/a〉

    Description: The Arabidopsis ABI1 locus is essential for a wide spectrum of abscisic acid (ABA) responses throughout plant development. Here, ABI1 was shown to regulate stomatal aperture in leaves and mitotic activity in root meristems. The ABI1 gene was cloned and predicted to encode a signaling protein. Although its carboxyl-terminal domain is related to serine-threonine phosphatase 2C, the ABI1 protein has a unique amino-terminal extension containing an EF hand calcium-binding site. These results suggest that the ABI1 protein is a Ca(2+)-modulated phosphatase and functions to integrate ABA and Ca2+ signals with phosphorylation-dependent response pathways.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Leung, J -- Bouvier-Durand, M -- Morris, P C -- Guerrier, D -- Chefdor, F -- Giraudat, J -- New York, N.Y. -- Science. 1994 Jun 3;264(5164):1448-52.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institut des Sciences Vegetales, Centre National de la Recherche Scientifique UPR 40, Gif-sur-Yvette, France.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7910981" target="_blank"〉PubMed〈/a〉

    Description: The pathogenesis of amoebic dysentery is a result of cytolysis of the colonic mucosa by the parasitic protozoan Entamoeba histolytica. The cytolysis results in extensive local ulceration and allows the amoeba to penetrate and metastasize to distant sites. Factors involved in this process were defined with three clones that express hemolytic activities in Escherichia coli. These potential amoebic virulence determinants were also toxic to human colonic epithelial cells, the primary cellular targets in amoebal invasion of the large intestine. The coding sequences for the hemolysins were close to each other on a 2.6-kilobase segment of a 25-kilobase extrachromosomal DNA element. The structural genes for the hemolysins were within inverted repeats that encode ribosomal RNAs.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Jansson, A -- Gillin, F -- Kagardt, U -- Hagblom, P -- New York, N.Y. -- Science. 1994 Mar 11;263(5152):1440-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Microbiology, Uppsala University, Sweden.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8128227" target="_blank"〉PubMed〈/a〉

    Description: The trimeric protein hemagglutinin (HA) of the influenza viral envelope is essential for cell entry. To investigate the interaction of HA with membranes, two 40-residue, cysteine-substituted peptides comprising the loop region and the first part of the coiled-coil stem were synthesized and modified with a nitroxide spin label. Electron paramagnetic resonance analysis revealed that the peptide inserts reversibly into phospholipid vesicles under endosomal pH conditions. This result suggests that some or all of the long coiled-coil trimer of HA may insert into membranes, which could bring the viral and cell membranes closer together and facilitate fusion.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Yu, Y G -- King, D S -- Shin, Y K -- New York, N.Y. -- Science. 1994 Oct 14;266(5183):274-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Chemistry, University of California, Berkeley.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7939662" target="_blank"〉PubMed〈/a〉

    Description: The 2;5 chromosomal translocation occurs in most anaplastic large-cell non-Hodgkin's lymphomas arising from activated T lymphocytes. This rearrangement was shown to fuse the NPM nucleolar phosphoprotein gene on chromosome 5q35 to a previously unidentified protein tyrosine kinase gene, ALK, on chromosome 2p23. In the predicted hybrid protein, the amino terminus of nucleophosmin (NPM) is linked to the catalytic domain of anaplastic lymphoma kinase (ALK). Expressed in the small intestine, testis, and brain but not in normal lymphoid cells, ALK shows greatest sequence similarity to the insulin receptor subfamily of kinases. Unscheduled expression of the truncated ALK may contribute to malignant transformation in these lymphomas.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Morris, S W -- Kirstein, M N -- Valentine, M B -- Dittmer, K G -- Shapiro, D N -- Saltman, D L -- Look, A T -- CA 21765/CA/NCI NIH HHS/ -- KO8 CA 01702/CA/NCI NIH HHS/ -- P01 CA 20180/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1994 Mar 4;263(5151):1281-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Experimental Oncology, St. Jude Children's Research Hospital, Memphis, TN 38105.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8122112" target="_blank"〉PubMed〈/a〉

    Description: The decay of excitatory postsynaptic currents in central neurons mediated by alpha-amino-3-hydroxy-5-methyl-4-isoxazole-propionate (AMPA) receptors is likely to be shaped either by receptor desensitization or by offset after removal of glutamate from the synaptic cleft. Native AMPA receptors show desensitization time constants of 1 to about 10 milliseconds, but the underlying molecular determinants of these large differences are unknown. Cloned AMPA receptors carrying the "flop" splice variants of glutamate receptor subtype C (GluR-C) and GluR-D are shown to have desensitization time constants of around 1 millisecond, whereas those with the "flip" variants are about four times slower. Cerebellar granule cells switch their expression of GluR-D splice variants from mostly flip forms in early stages to predominantly flop forms in the adult rat brain. These findings suggest that rapid desensitization of AMPA receptors can be regulated by the expression and alternative splicing of GluR-D gene transcripts.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Mosbacher, J -- Schoepfer, R -- Monyer, H -- Burnashev, N -- Seeburg, P H -- Ruppersberg, J P -- Wellcome Trust/United Kingdom -- New York, N.Y. -- Science. 1994 Nov 11;266(5187):1059-62.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Max-Planck-Institut fur medizinische Forschung, Heidelberg, Germany.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7973663" target="_blank"〉PubMed〈/a〉

    Description: The role of protein degradation in mitochondrial homeostasis was explored by cloning of a gene from Saccharomyces cerevisiae that encodes a protein resembling the adenosine triphosphate (ATP)-dependent bacterial protease Lon. The predicted yeast protein has a typical mitochondrial matrix-targeting sequence at its amino terminus. Yeast cells lacking a functional LON gene contained a nonfunctional mitochondrial genome, were respiratory-deficient, and lacked an ATP-dependent proteolytic activity present in the mitochondria of Lon+ cells. Lon- cells were also impaired in their ability to catalyze the energy-dependent degradation of several mitochondrial matrix proteins and they accumulated electron-dense inclusions in their mitochondrial matrix.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Suzuki, C K -- Suda, K -- Wang, N -- Schatz, G -- New York, N.Y. -- Science. 1994 Apr 8;264(5156):273-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Biozentrum der Universitat Basel, Switzerland.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8146662" target="_blank"〉PubMed〈/a〉

    Description: The first step in oral absorption of many medically important peptide-based drugs is mediated by an intestinal proton-dependent peptide transporter. This transporter facilitates the oral absorption of beta-lactam antibiotics and angiotensin-converting enzyme inhibitors from the intestine into enterocytes lining the luminal wall. A monoclonal antibody that blocked uptake of cephalexin was used to identify and clone a gene that encodes an approximately 92-kilodalton membrane protein that was associated with the acquisition of peptide transport activity by transport-deficient cells. The amino acid sequence deduced from the complementary DNA sequence of the cloned gene indicated that this transport-associated protein shares several conserved structural elements with the cadherin superfamily of calcium-dependent, cell-cell adhesion proteins.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Dantzig, A H -- Hoskins, J A -- Tabas, L B -- Bright, S -- Shepard, R L -- Jenkins, I L -- Duckworth, D C -- Sportsman, J R -- Mackensen, D -- Rosteck, P R Jr -- New York, N.Y. -- Science. 1994 Apr 15;264(5157):430-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Lilly Research Laboratories, Eli Lilly and Company, Indianapolis, IN 46285.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8153632" target="_blank"〉PubMed〈/a〉

    Description: Specific protein-ligand interactions are critical for cellular function, and most proteins select their partners with sharp discrimination. However, the oligopeptide-binding protein of Salmonella typhimurium (OppA) binds peptides of two to five amino acid residues without regard to sequence. The crystal structure of OppA reveals a three-domain organization, unlike other periplasmic binding proteins. In OppA-peptide complexes, the ligands are completely enclosed in the protein interior, a mode of binding that normally imposes tight specificity. The protein fulfills the hydrogen bonding and electrostatic potential of the ligand main chain and accommodates the peptide side chains in voluminous hydrated cavities.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Tame, J R -- Murshudov, G N -- Dodson, E J -- Neil, T K -- Dodson, G G -- Higgins, C F -- Wilkinson, A J -- New York, N.Y. -- Science. 1994 Jun 10;264(5165):1578-81.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Chemistry, University of York, UK.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8202710" target="_blank"〉PubMed〈/a〉

    Description: Structures of the 31-kilodalton catalytic domain of rat DNA polymerase beta (pol beta) and the whole 39-kilodalton enzyme were determined at 2.3 and 3.6 angstrom resolution, respectively. The 31-kilodalton domain is composed of fingers, palm, and thumb subdomains arranged to form a DNA binding channel reminiscent of the polymerase domains of the Klenow fragment of Escherichia coli DNA polymerase I, HIV-1 reverse transcriptase, and bacteriophage T7 RNA polymerase. The amino-terminal 8-kilodalton domain is attached to the fingers subdomain by a flexible hinge. The two invariant aspartates found in all polymerase sequences and implicated in catalytic activity have the same geometric arrangement within structurally similar but topologically distinct palms, indicating that the polymerases have maintained, or possibly re-evolved, a common nucleotidyl transfer mechanism. The location of Mn2+ and deoxyadenosine triphosphate in pol beta confirms the role of the invariant aspartates in metal ion and deoxynucleoside triphosphate binding.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sawaya, M R -- Pelletier, H -- Kumar, A -- Wilson, S H -- Kraut, J -- CA17374/CA/NCI NIH HHS/ -- ES06839/ES/NIEHS NIH HHS/ -- GM10928/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1994 Jun 24;264(5167):1930-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Chemistry, University of California, San Diego 92093-0317.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7516581" target="_blank"〉PubMed〈/a〉

    Description: The role played in immune surveillance by gamma delta T cells residing in various epithelia has not been clear. It is shown here that activated gamma delta T cells obtained from skin and intestine express the epithelial cell mitogen keratinocyte growth factor (KGF). In contrast, intraepithelial alpha beta T cells, as well as all lymphoid alpha beta and gamma delta T cell populations tested, did not produce KGF or promote the growth of cultured epithelial cells. These results suggest that intraepithelial gamma delta T cells function in surveillance and in repair of damaged epithelial tissues.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Boismenu, R -- Havran, W L -- AI32751/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 1994 Nov 18;266(5188):1253-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Immunology, Scripps Research Institute, La Jolla, CA 92037.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7973709" target="_blank"〉PubMed〈/a〉

    Description: Concentration of urine in mammals is regulated by the antidiuretic hormone vasopressin. Binding of vasopressin to its V2 receptor leads to the insertion of water channels in apical membranes of principal cells in collecting ducts. In nephrogenic diabetes insipidus (NDI), the kidney fails to concentrate urine in response to vasopressin. A male patient with an autosomal recessive form of NDI was found to be a compound heterozygote for two mutations in the gene encoding aquaporin-2, a water channel. Functional expression studies in Xenopus oocytes revealed that each mutation resulted in nonfunctional water channel proteins. Thus, aquaporin-2 is essential for vasopressin-dependent concentration of urine.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Deen, P M -- Verdijk, M A -- Knoers, N V -- Wieringa, B -- Monnens, L A -- van Os, C H -- van Oost, B A -- New York, N.Y. -- Science. 1994 Apr 1;264(5155):92-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Cell Physiology, University of Nijmegen, Netherlands.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8140421" target="_blank"〉PubMed〈/a〉

    Description: The three-dimensional structure of a ternary complex of the purine repressor, PurR, bound to both its corepressor, hypoxanthine, and the 16-base pair purF operator site has been solved at 2.7 A resolution by x-ray crystallography. The bipartite structure of PurR consists of an amino-terminal DNA-binding domain and a larger carboxyl-terminal corepressor binding and dimerization domain that is similar to that of the bacterial periplasmic binding proteins. The DNA-binding domain contains a helix-turn-helix motif that makes base-specific contacts in the major groove of the DNA. Base contacts are also made by residues of symmetry-related alpha helices, the "hinge" helices, which bind deeply in the minor groove. Critical to hinge helix-minor groove binding is the intercalation of the side chains of Leu54 and its symmetry-related mate, Leu54', into the central CpG-base pair step. These residues thereby act as "leucine levers" to pry open the minor groove and kink the purF operator by 45 degrees.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Schumacher, M A -- Choi, K Y -- Zalkin, H -- Brennan, R G -- GM 24658/GM/NIGMS NIH HHS/ -- GM 49244/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1994 Nov 4;266(5186):763-70.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biochemistry and Molecular Biology, Oregon Health Sciences University, Portland 97201-3098.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7973627" target="_blank"〉PubMed〈/a〉

    Description: A homozygous mutation in the kinase domain of ZAP-70, a T cell receptor-associated protein tyrosine kinase, produced a distinctive form of human severe combined immunodeficiency. Manifestations of this disorder included profound immunodeficiency, absence of peripheral CD8+ T cells, and abundant peripheral CD4+ T cells that were refractory to T cell receptor-mediated activation. These findings demonstrate that ZAP-70 is essential for human T cell function and suggest that CD4+ and CD8+ T cells depend on different intracellular signaling pathways to support their development or survival.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Elder, M E -- Lin, D -- Clever, J -- Chan, A C -- Hope, T J -- Weiss, A -- Parslow, T G -- AI29313/AI/NIAID NIH HHS/ -- GM43574/GM/NIGMS NIH HHS/ -- RR01271/RR/NCRR NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1994 Jun 10;264(5165):1596-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Pediatrics, University of California, San Francisco 94143-0110.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8202712" target="_blank"〉PubMed〈/a〉

    Description: The most frequently occurring resistance of Gram-negative bacteria against tetracyclines is triggered by drug recognition of the Tet repressor. This causes dissociation of the repressor-operator DNA complex and enables expression of the resistance protein TetA, which is responsible for active efflux of tetracycline. The 2.5 angstrom resolution crystal structure of the homodimeric Tet repressor complexed with tetracycline-magnesium reveals detailed drug recognition. The orientation of the operator-binding helix-turn-helix motifs of the repressor is inverted in comparison with other DNA binding proteins. The repressor-drug complex is unable to interact with DNA because the separation of the DNA binding motifs is 5 angstroms wider than usually observed.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hinrichs, W -- Kisker, C -- Duvel, M -- Muller, A -- Tovar, K -- Hillen, W -- Saenger, W -- New York, N.Y. -- Science. 1994 Apr 15;264(5157):418-20.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institut fur Kristallographie, Freie Universitat Berlin, Germany.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8153629" target="_blank"〉PubMed〈/a〉

    Description: The plant hormone abscisic acid (ABA) mediates various responses such as stomatal closure, the maintenance of seed dormancy, and the inhibition of plant growth. All three responses are affected in the ABA-insensitive mutant abi1 of Arabidopsis thaliana, suggesting that an early step in the signaling of ABA is controlled by the ABI1 locus. The ABI1 gene was cloned by chromosome walking, and a missense mutation was identified in the structural gene of the abi1 mutant. The ABI1 gene encodes a protein with high similarity to protein serine or threonine phosphatases of type 2C with the novel feature of a putative Ca2+ binding site. Thus, the control of the phosphorylation state of cell signaling components by the ABI1 product could mediate pleiotropic hormone responses.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Meyer, K -- Leube, M P -- Grill, E -- New York, N.Y. -- Science. 1994 Jun 3;264(5164):1452-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institute of Plant Sciences, Swiss Federal Institute of Technology, Zurich.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8197457" target="_blank"〉PubMed〈/a〉

    Description: Thermodynamic studies have demonstrated the central importance of a large negative heat capacity change (delta C degree assoc) in site-specific protein-DNA recognition. Dissection of the large negative delta C degree assoc and the entropy change of protein-ligand and protein-DNA complexation provide a thermodynamic signature identifying processes in which local folding is coupled to binding. Estimates of the number of residues that fold on binding obtained from this analysis agree with structural data. Structural comparisons indicate that these local folding transitions create key parts of the protein-DNA interface. The energetic implications of this "induced fit" model for DNA site recognition are considered.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Spolar, R S -- Record, M T Jr -- GM23467/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1994 Feb 11;263(5148):777-84.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Chemistry, University of Wisconsin-Madison 53706.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8303294" target="_blank"〉PubMed〈/a〉

    Description: Interleukin-8 (IL-8), a pro-inflammatory protein, has been shown by nuclear magnetic resonance (NMR) and x-ray techniques to exist as a homodimer. An IL-8 analog was chemically synthesized, with the amide nitrogen of leucine-25 methylated to selectivity block formation of hydrogen bonds between monomers and thereby prevent dimerization. This analog was shown to be a monomer, as assessed by analytical ultracentrifugation and NMR. Nevertheless, it was equivalent to IL-8 in assays of neutrophil activation, which indicates that the monomer is a functional form of IL-8.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rajarathnam, K -- Sykes, B D -- Kay, C M -- Dewald, B -- Geiser, T -- Baggiolini, M -- Clark-Lewis, I -- New York, N.Y. -- Science. 1994 Apr 1;264(5155):90-2.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Protein Engineering Network of Centres of Excellence (PENCE), University of Alberta, Edmonton, Canada.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8140420" target="_blank"〉PubMed〈/a〉

    Description: Interleukin-4 (IL-4) is an immunomodulatory cytokine secreted by activated T lymphocytes, basophils, and mast cells. It plays an important role in modulating the balance of T helper (Th) cell subsets, favoring expansion of the Th2 lineage relative to Th1. Imbalance of these T lymphocyte subsets has been implicated in immunological diseases including allergy, inflammation, and autoimmune disease. IL-4 may mediate its biological effects, at least in part, by activating a tyrosine-phosphorylated DNA binding protein. This protein has now been purified and its encoding gene cloned. Examination of the primary amino acid sequence of this protein indicates that it is a member of the signal transducers and activators of transcription (Stat) family of DNA binding proteins, hereby designated IL-4 Stat. Study of the inhibitory activities of phosphotyrosine-containing peptides derived from the intracellular domain of the IL-4 receptor provided evidence for direct coupling of receptor and transcription factor during the IL-4 Stat activation cycle. Such observations indicate that IL-4 Stat has the same functional domain for both receptor coupling and dimerization.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hou, J -- Schindler, U -- Henzel, W J -- Ho, T C -- Brasseur, M -- McKnight, S L -- New York, N.Y. -- Science. 1994 Sep 16;265(5179):1701-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Tularik, Inc., South San Francisco, CA 94080.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8085155" target="_blank"〉PubMed〈/a〉

It has served as a model system for genetic and biochemical analysis of protein folding. The x-ray structure of a shortened TSP (residues 109 to 666) was determined to a 2.0 angstrom resolution. Each subunit of the homotrimer contains a large parallel beta helix. The interdigitation of the polypeptide chains at the carboxyl termini is important to protrimer formation in the folding pathway and to thermostability of the mature protein.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Steinbacher, S -- Seckler, R -- Miller, S -- Steipe, B -- Huber, R -- Reinemer, P -- New York, N.Y. -- Science. 1994 Jul 15;265(5170):383-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Max-Planck-Institut fur Biochemie, Abteilung Strukturforschung, Martinsried, Germany.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8023158" target="_blank"〉PubMed〈/a〉

    Description: Trans-activator (Tat) proteins regulate the transcription of lentiviral DNA in the host cell genome. These RNA binding proteins participate in the life cycle of all known lentiviruses, such as the human immunodeficiency viruses (HIV) or the equine infectious anemia virus (EIAV). The consensus RNA binding motifs [the trans-activation responsive element (TAR)] of HIV-1 as well as EIAV Tat proteins are well characterized. The structure of the 75-amino acid EIAV Tat protein in solution was determined by two- and three-dimensional nuclear magnetic resonance methods and molecular dynamics calculations. The protein structure exhibits a well-defined hydrophobic core of 15 amino acids that serves as a scaffold for two flexible domains corresponding to the NH2- and COOH-terminal regions. The core region is a strictly conserved sequence region among the known Tat proteins. The structural data can be used to explain several of the observed features of Tat proteins.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Willbold, D -- Rosin-Arbesfeld, R -- Sticht, H -- Frank, R -- Rosch, P -- New York, N.Y. -- Science. 1994 Jun 10;264(5165):1584-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Lehrstuhl fur Biopolymere, Universitat Bayreuth, Germany.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7515512" target="_blank"〉PubMed〈/a〉

    Description: RNA polymerase I and II transcription factors SL1 and TFIID, respectively, are composed of the TATA-binding protein (TBP) and a set of TBP-associated factors (TAFs) responsible for promoter recognition. How the universal transcription factor TBP becomes committed to a TFIID or SL1 complex has not been known. Complementary DNAs encoding each of the three TAFIs that are integral components of SL1 have not been isolated. Analysis of subunit interactions indicated that the three TAFIs can bind individually and specifically to TBP. In addition, these TAFIs interact with each other to form a stable TBP-TAF complex. When TBP was bound first by either TAFI110, 63, or 48, subunits of TFIID such as TAFII250 and 150 did not bind TBP. Conversely, if TBP first formed a complex with TAFII250 or 150, the subunits of SL1 did not bind TBP. These results suggest that a mutually exclusive binding specificity for TBP intrinsic to SL1 and TFIID subunits directs the formation of promoter- and RNA polymerase-selective TBP-TAF complexes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Comai, L -- Zomerdijk, J C -- Beckmann, H -- Zhou, S -- Admon, A -- Tjian, R -- New York, N.Y. -- Science. 1994 Dec 23;266(5193):1966-72.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute, Department of Molecular and Cell Biology, University of California at Berkeley 94720-3204.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7801123" target="_blank"〉PubMed〈/a〉

    Description: A four-ring tripeptide containing alternating imidazole and pyrrole carboxamides specifically binds six-base pair 5'-(A,T)GCGC(A,T)-3' sites in the minor groove of DNA. The designed peptide has a specificity completely reversed from that of the tripyrrole distamycin, which binds A,T sequences. Structural studies with nuclear magnetic resonance revealed that two peptides bound side-by-side and in an antiparallel orientation in the minor groove. Each of the four imidazoles in the 2:1 ligand-DNA complex recognized a specific guanine amino group in the GCGC core through a hydrogen bond. Targeting a designated four-base pair G.C tract by this synthetic ligand supports the generality of the 2:1 peptide-DNA motif for sequence-specific minor groove recognition of DNA.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Geierstanger, B H -- Mrksich, M -- Dervan, P B -- Wemmer, D E -- GM-27681/GM/NIGMS NIH HHS/ -- GM-43129/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1994 Oct 28;266(5185):646-50.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Graduate Group in Biophysics, University of California, Berkeley 94720.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7939719" target="_blank"〉PubMed〈/a〉

    Description: Plant disease resistance genes function is highly specific pathogen recognition pathways. PRS2 is a resistance gene of Arabidopsis thaliana that confers resistance against Pseudomonas syringae bacteria that express avirulence gene avrRpt2. RPS2 was isolated by the use of a positional cloning strategy. The derived amino acid sequence of RPS2 contains leucine-rich repeat, membrane-spanning, leucine zipper, and P loop domains. The function of the RPS2 gene product in defense signal transduction is postulated to involve nucleotide triphosphate binding and protein-protein interactions and may also involve the reception of an elicitor produced by the avirulent pathogen.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bent, A F -- Kunkel, B N -- Dahlbeck, D -- Brown, K L -- Schmidt, R -- Giraudat, J -- Leung, J -- Staskawicz, B J -- New York, N.Y. -- Science. 1994 Sep 23;265(5180):1856-60.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Plant Biology, University of California, Berkeley 94720.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8091210" target="_blank"〉PubMed〈/a〉

    Description: The crystal structure of a complex between a 24-amino acid peptide from the third variable (V3) loop of human immunodeficiency virus-type 1 (HIV-1) gp 120 and the Fab fragment of a broadly neutralizing antibody (59.1) was determined to 3 angstrom resolution. The tip of the V3 loop containing the Gly-Pro-Gly-Arg-Ala-Phe sequence adopts a double-turn conformation, which may be the basis of its conservation in many HIV-1 isolates. A complete map of the HIV-1 principal neutralizing determinant was constructed by stitching together structures of V3 loop peptides bound to 59.1 and to an isolate-specific (MN) neutralizing antibody (50.1). Structural conservation of the overlapping epitopes suggests that this biologically relevant conformation could be of use in the design of synthetic vaccines and drugs to inhibit HIV-1 entry and virus-related cellular fusion.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ghiara, J B -- Stura, E A -- Stanfield, R L -- Profy, A T -- Wilson, I A -- GM-46192/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1994 Apr 1;264(5155):82-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular Biology, Scripps Research Institute, La Jolla, CA 92037.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7511253" target="_blank"〉PubMed〈/a〉

    Description: A Candida albicans gene (CPH1) was cloned that encodes a protein homologous to Saccharomyces cerevisiae Ste12p, a transcription factor that is the target of the pheromone response mitogen-activated protein kinase cascade. CPH1 complements both the mating defect of ste12 haploids and the filamentous growth defect of ste12/ste12 diploids. Candida albicans strains without a functional CPH1 gene (cph1/cph1) show suppressed hyphal formation on solid medium. However, cph1/cph1 strains can still form hyphae in liquid culture and in response to serum. Thus, filamentous growth may be activated in C. albicans by the same signaling kinase cascade that activates Ste12p in S. cerevisiae; however, alternative pathways may exist in C. albicans.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Liu, H -- Kohler, J -- Fink, G R -- GM402661/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1994 Dec 9;266(5191):1723-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Whitehead Institute for Biomedical Research, Cambridge, MA 02142.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7992058" target="_blank"〉PubMed〈/a〉

    Description: The TATA-binding protein TBP appears to be essential for all transcription in eukaryotic cell nuclei, which suggests that its function was established early in evolution. Archaebacteria constitute a kingdom of organisms distinct from eukaryotes and eubacteria. Archaebacterial gene regulatory sequences often map to TATA box-like motifs. Here it is shown that the archaebacterium Pyrococcus woesei expresses a protein with structural and functional similarity to eukaryotic TBP molecules. This suggests that TBP's role in transcription was established before the archaebacterial and eukaryotic lineages diverged and that the transcription systems of archaebacteria and eukaryotes are fundamentally homologous.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rowlands, T -- Baumann, P -- Jackson, S P -- Wellcome Trust/United Kingdom -- New York, N.Y. -- Science. 1994 May 27;264(5163):1326-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Wellcome/CRC Institute, Cambridge, UK.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8191287" target="_blank"〉PubMed〈/a〉

    Description: The three-dimensional structure of an unusually active hydrolytic antibody with a phosphonate transition state analog (hapten) bound to the active site has been solved to 2.5 A resolution. The antibody (17E8) catalyzes the hydrolysis of norleucine and methionine phenyl esters and is selective for amino acid esters that have the natural alpha-carbon L configuration. A plot of the pH-dependence of the antibody-catalyzed reaction is bell-shaped with an activity maximum at pH 9.5; experiments on mechanism lend support to the formation of a covalent acyl-antibody intermediate. The structural and kinetic data are complementary and support a hydrolytic mechanism for the antibody that is remarkably similar to that of the serine proteases. The antibody active site contains a Ser-His dyad structure proximal to the phosphorous atom of the bound hapten that resembles two of the three components of the Ser-His-Asp catalytic triad of serine proteases. The antibody active site also contains a Lys residue to stabilize oxyanion formation, and a hydrophobic binding pocket for specific substrate recognition of norleucine and methionine side chains. The structure identifies active site residues that mediate catalysis and suggests specific mutations that may improve the catalytic efficiency of the antibody. This high resolution structure of a catalytic antibody-hapten complex shows that antibodies can converge on active site structures that have arisen through natural enzyme evolution.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Zhou, G W -- Guo, J -- Huang, W -- Fletterick, R J -- Scanlan, T S -- DK39304/DK/NIDDK NIH HHS/ -- New York, N.Y. -- Science. 1994 Aug 19;265(5175):1059-64.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biochemistry and Biophysics, University of California, San Francisco 94143-0448.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8066444" target="_blank"〉PubMed〈/a〉

    Description: Inwardly rectifying potassium (K+) channels (IRKs) maintain the resting membrane potential of cells and permit prolonged depolarization, such as during the cardiac action potential. Inward rectification may result from block of the ion conduction pore by intracellular magnesium (Mgi2+). Two members of this family, IRK1 and ROMK1, which share 40 percent amino acid identity, differ markedly in single-channel K+ conductance and sensitivity to block by Mgi2+. The conserved H5 regions were hypothesized to determine these pore properties because they have this function in voltage-dependent K+ channels and in cyclic nucleotide-gated channels. However, exchange of the H5 region between IRK1 and ROMK1 had no effect on rectification and little or no effect on K+ conductance. By contrast, exchange of the amino- and carboxyl-terminal regions together transferred Mg2+ blockade and K+ conductance of IRK1 to ROMK1. Exchange of the carboxyl but not the amino terminus had a similar effect. Therefore, the carboxyl terminus appears to have a major role in specifying the pore properties of IRKs.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Taglialatela, M -- Wible, B A -- Caporaso, R -- Brown, A M -- HL36930/HL/NHLBI NIH HHS/ -- HL37044/HL/NHLBI NIH HHS/ -- NS23877/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 1994 May 6;264(5160):844-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular Physiology and Biophysics, Baylor College of Medicine, Houston, TX 77030.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8171340" target="_blank"〉PubMed〈/a〉

The function of the 100-amino acid protein product of rolA is unknown, although its expression causes physiological and developmental alterations in transgenic plants. The rolA gene of A. rhizogenes contains an intron in its untranslated leader region that has features typical of plant pre-messenger RNA introns. Transcription and splicing of the rolA pre-messenger RNA occur in the plant cell.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Magrelli, A -- Langenkemper, K -- Dehio, C -- Schell, J -- Spena, A -- New York, N.Y. -- Science. 1994 Dec 23;266(5193):1986-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Max-Plank-Institut fur Zuchtungsforschung, Cologne, Germany.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7528444" target="_blank"〉PubMed〈/a〉

    Description: Proteasomes are the proteolytic complex responsible for major histocompatibility complex (MHC) class I-restricted antigen presentation. Interferon gamma treatment increases expression MHC-encoded LMP2 and LMP7 subunits of the proteasome and decreases expression of two proteasome subunits, named X and Y, which alters the proteolytic specificity of proteasomes. Molecular cloning of complementary DNAs encoding X and Y showed that their proteins are proteasomal subunits with high amino acid similarity to LMP7 and LMP2, respectively. Thus, interferon gamma may induce subunit replacements of X and Y by LMP7 and LMP2, respectively, producing proteasomes perhaps more appropriate for the immunological processing of endogenous antigens.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Akiyama, K -- Yokota, K -- Kagawa, S -- Shimbara, N -- Tamura, T -- Akioka, H -- Nothwang, H G -- Noda, C -- Tanaka, K -- Ichihara, A -- New York, N.Y. -- Science. 1994 Aug 26;265(5176):1231-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Urology, School of Medicine, University of Tokushima, Japan.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8066462" target="_blank"〉PubMed〈/a〉

    Description: A synthetic combinatorial library containing 52,128,400 D-amino acid hexapeptides was used to identify a ligand for the mu opioid receptor. The peptide, Ac-rfwink-NH2, bears no resemblance to any known opioid peptide. Simulations using molecular dynamics, however, showed that three amino acid moieties have the same spatial orientation as the corresponding pharmacophoric groups of the opioid peptide PLO17. Ac-rfwink-NH2 was shown to be a potent agonist at the mu receptor and induced long-lasting analgesia in mice. Analgesia produced by intraperitoneally administered Ac-rfwink-NH2 was blocked by intracerebroventricular administration of naloxone, demonstrating that this peptide may cross the blood-brain barrier.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Dooley, C T -- Chung, N N -- Wilkes, B C -- Schiller, P W -- Bidlack, J M -- Pasternak, G W -- Houghten, R A -- DA-000138/DA/NIDA NIH HHS/ -- DA-02615/DA/NIDA NIH HHS/ -- DA-03742/DA/NIDA NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1994 Dec 23;266(5193):2019-22.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Torrey Pines Institute for Molecular Studies, San Diego, CA 92121.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7801131" target="_blank"〉PubMed〈/a〉

    Description: The crystal structure of a 27-kilodalton methylcobalamin-containing fragment of methionine synthase from Escherichia coli was determined at 3.0 A resolution. This structure depicts cobalamin-protein interactions and reveals that the corrin macrocycle lies between a helical amino-terminal domain and an alpha/beta carboxyl-terminal domain that is a variant of the Rossmann fold. Methylcobalamin undergoes a conformational change on binding the protein; the dimethylbenzimidazole group, which is coordinated to the cobalt in the free cofactor, moves away from the corrin and is replaced by a histidine contributed by the protein. The sequence Asp-X-His-X-X-Gly, which contains this histidine ligand, is conserved in the adenosylcobalamin-dependent enzymes methylmalonyl-coenzyme A mutase and glutamate mutase, suggesting that displacement of the dimethylbenzimidazole will be a feature common to many cobalamin-binding proteins. Thus the cobalt ligand, His759, and the neighboring residues Asp757 and Ser810, may form a catalytic quartet, Co-His-Asp-Ser, that modulates the reactivity of the B12 prosthetic group in methionine synthase.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Drennan, C L -- Huang, S -- Drummond, J T -- Matthews, R G -- Lidwig, M L -- GM08570/GM/NIGMS NIH HHS/ -- GM16429/GM/NIGMS NIH HHS/ -- GM24908/GM/NIGMS NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1994 Dec 9;266(5191):1669-74.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Biophysics Research Division, University of Michigan, Ann Arbor 48109-1055.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7992050" target="_blank"〉PubMed〈/a〉

    Description: Growth factor receptor-bound protein 2 (Grb2) links tyrosine-phosphorylated proteins to a guanine nucleotide releasing factor of the son of sevenless (Sos) class by attaching to the former by its Src homology 2 (SH2) moiety and to the latter by its SH3 domains. An isoform of grb2 complementary DNA (cDNA) was cloned that has a deletion in the SH2 domain. The protein encoded by this cDNA, Grb3-3, did not bind to phosphorylated epidermal growth factor receptor (EGFR) but retained functional SH3 domains and inhibited EGF-induced transactivation of a Ras-responsive element. The messenger RNA encoding Grb3-3 was expressed in high amounts in the thymus of rats at an age when massive negative selection of thymocytes occurs. Microinjection of Grb3-3 into Swiss 3T3 fibroblasts induced apoptosis. These findings indicate that Grb3-3, by acting as a dominant negative protein over Grb2 and by suppressing proliferative signals, may trigger active programmed cell death.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Fath, I -- Schweighoffer, F -- Rey, I -- Multon, M C -- Boiziau, J -- Duchesne, M -- Tocque, B -- New York, N.Y. -- Science. 1994 May 13;264(5161):971-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Rhone-Poulenc Rorer, Centre de Recherche de Vitry-Alfortville, Vitry sur Seine, France.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8178156" target="_blank"〉PubMed〈/a〉

    Description: The structure of the 52-amino acid DNA-binding domain of the prokaryotic Hin recombinase, complexed with a DNA recombination half-site, has been solved by x-ray crystallography at 2.3 angstrom resolution. The Hin domain consists of a three-alpha-helix bundle, with the carboxyl-terminal helix inserted into the major groove of DNA, and two flanking extended polypeptide chains that contact bases in the minor groove. The overall structure displays features resembling both a prototypical bacterial helix-turn-helix and the eukaryotic homeodomain, and in many respects is an intermediate between these two DNA-binding motifs. In addition, a new structural motif is seen: the six-amino acid carboxyl-terminal peptide of the Hin domain runs along the minor groove at the edge of the recombination site, with the peptide backbone facing the floor of the groove and side chains extending away toward the exterior. The x-ray structure provides an almost complete explanation for DNA mutant binding studies in the Hin system and for DNA specificity observed in the Hin-related family of DNA invertases.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Feng, J A -- Johnson, R C -- Dickerson, R E -- GM-31299/GM/NIGMS NIH HHS/ -- GM-38509/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1994 Jan 21;263(5145):348-55.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Molecular Biology Institute, University of California, Los Angeles 90024.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8278807" target="_blank"〉PubMed〈/a〉

    Description: The three-dimensional structure of a Staphylococcus aureus superantigen, toxic shock syndrome toxin-1 (TSST-1), complexed with a human class II major histocompatibility molecule (DR1), was determined by x-ray crystallography. The TSST-1 binding site on DR1 overlaps that of the superantigen S. aureus enterotoxin B (SEB), but the two binding modes differ. Whereas SEB binds primarily off one edge of the peptide binding site of DR1, TSST-1 extends over almost one-half of the binding site and contacts both the flanking alpha helices of the histocompatibility antigen and the bound peptide. This difference suggests that the T cell receptor (TCR) would bind to TSST-1:DR1 very differently than to DR1:peptide or SEB:DR1. It also suggests that TSST-1 binding may be dependent on the peptide, though less so than TCR binding, providing a possible explanation for the inability of TSST-1 to competitively block SEB binding to all DR1 molecules on cells (even though the binding sites of TSST-1 and SEB on DR1 overlap almost completely) and suggesting the possibility that T cell activation by superantigen could be directed by peptide antigen.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kim, J -- Urban, R G -- Strominger, J L -- Wiley, D C -- New York, N.Y. -- Science. 1994 Dec 16;266(5192):1870-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute, Children's Hospital, Boston, MA 02115.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7997880" target="_blank"〉PubMed〈/a〉

    Description: Medical genetics was revolutionized during the 1980s by the application of genetic mapping to locate the genes responsible for simple Mendelian diseases. Most diseases and traits, however, do not follow simple inheritance patterns. Genetics have thus begun taking up the even greater challenge of the genetic dissection of complex traits. Four major approaches have been developed: linkage analysis, allele-sharing methods, association studies, and polygenic analysis of experimental crosses. This article synthesizes the current state of the genetic dissection of complex traits--describing the methods, limitations, and recent applications to biological problems.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lander, E S -- Schork, N J -- HG00098/HG/NHGRI NIH HHS/ -- New York, N.Y. -- Science. 1994 Sep 30;265(5181):2037-48.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Whitehead Institute for Biomedical Research, Cambridge, MA 02142.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8091226" target="_blank"〉PubMed〈/a〉

    Description: Isoniazid (isonicotinic acid hydrazide, INH) is one of the most widely used antituberculosis drugs, yet its precise target of action on Mycobacterium tuberculosis is unknown. A missense mutation within the mycobacterial inhA gene was shown to confer resistance to both INH and ethionamide (ETH) in M. smegmatis and in M. bovis. The wild-type inhA gene also conferred INH and ETH resistance when transferred on a multicopy plasmid vector to M. smegmatis and M. bovis BCG. The InhA protein shows significant sequence conservation with the Escherichia coli enzyme EnvM, and cell-free assays indicate that it may be involved in mycolic acid biosynthesis. These results suggest that InhA is likely a primary target of action for INH and ETH.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Banerjee, A -- Dubnau, E -- Quemard, A -- Balasubramanian, V -- Um, K S -- Wilson, T -- Collins, D -- de Lisle, G -- Jacobs, W R Jr -- AI27160/AI/NIAID NIH HHS/ -- UO1AI30189/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 1994 Jan 14;263(5144):227-30.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute, Albert Einstein College of Medicine, Bronx, NY 10461.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8284673" target="_blank"〉PubMed〈/a〉

    Description: A phage display system was developed and used to select zinc finger proteins with altered DNA-binding specificities. The three zinc fingers of the Zif268 protein were expressed on the surface of filamentous phage, and a library of variants was prepared by randomizing critical amino acids in the first zinc finger. Affinity selections, using DNA sites with base changes in the region recognized by the first finger, yielded Zif268 variants that bound tightly and specifically to the new sites. This phage system provides a tool for the study of protein-DNA interactions and may offer a general method for selecting zinc finger proteins that recognize desired target sites on double-stranded DNA.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rebar, E J -- Pabo, C O -- New York, N.Y. -- Science. 1994 Feb 4;263(5147):671-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biology, Massachusetts Institute of Technology, Cambridge 02139.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8303274" target="_blank"〉PubMed〈/a〉

    Description: Para-hydroxybenzoate hydroxylase inserts oxygen into substrates by means of the labile intermediate, flavin C(4a)-hydroperoxide. This reaction requires transient isolation of the flavin and substrate from the bulk solvent. Previous crystal structures have revealed the position of the substrate para-hydroxybenzoate during oxygenation but not how it enters the active site. In this study, enzyme structures with the flavin ring displaced relative to the protein were determined, and it was established that these or similar flavin conformations also occur in solution. Movement of the flavin appears to be essential for the translocation of substrates and products into the solvent-shielded active site during catalysis.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gatti, D L -- Palfey, B A -- Lah, M S -- Entsch, B -- Massey, V -- Ballou, D P -- Ludwig, M L -- GM 11106/GM/NIGMS NIH HHS/ -- GM 16429/GM/NIGMS NIH HHS/ -- GM 20877/GM/NIGMS NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1994 Oct 7;266(5182):110-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biological Chemistry, University of Michigan, Ann Arbor 48109.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7939628" target="_blank"〉PubMed〈/a〉

    Description: Crystal structures of seryl-tRNA synthetase from Thermus thermophilus complexed with two different analogs of seryl adenylate have been determined at 2.5 A resolution. The first complex is between the enzyme and seryl-hydroxamate-AMP (adenosine monophosphate), produced enzymatically in the crystal from adenosine triphosphate (ATP) and serine hydroxamate, and the second is with a synthetic analog of seryl adenylate (5'-O-[N-(L-seryl)-sulfamoyl]adenosine), which is a strong inhibitor of the enzyme. Both molecules are bound in a similar fashion by a network of hydrogen bond interactions in a deep hydrophilic cleft formed by the antiparallel beta sheet and surrounding loops of the synthetase catalytic domain. Four regions in the primary sequence are involved in the interactions, including the motif 2 and 3 regions of class 2 synthetases. Apart from the specific recognition of the serine side chain, the interactions are likely to be similar in all class 2 synthetases.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Belrhali, H -- Yaremchuk, A -- Tukalo, M -- Larsen, K -- Berthet-Colominas, C -- Leberman, R -- Beijer, B -- Sproat, B -- Als-Nielsen, J -- Grubel, G -- New York, N.Y. -- Science. 1994 Mar 11;263(5152):1432-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉EMBL Grenoble Outstation, France.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8128224" target="_blank"〉PubMed〈/a〉

    Description: Pulse-probe transient Raman spectroscopy, with probe excitation at 230 nanometers, reveals changes in signals arising from tyrosine and tryptophan residues of the hemoglobin molecule as it moves from the relaxed (R) to the tense (T) state after photodeligation. Signals associated with intersubunit contacts in the T state develop in about 10 microseconds but are preceded by quite different signals, which reach maximum amplitude in about 50 nanoseconds. These signals involve the interior tryptophan residues that bridge the A and E helices by means of H bonds between the indole rings and serine or threonine side chains. Alterations of the H bond strengths, as a result of interhelix motions, can account for the signals. A model is proposed here in which loss of the ligand from the heme binding pocket is concerted with inward motion of the adjacent E helix; this motion, along with a complementary motion of the proximal F helix, transmits the energy associated with heme deligation to the subunit interfaces, leading to the T state rearrangement.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rodgers, K R -- Spiro, T G -- GM 25158/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1994 Sep 16;265(5179):1697-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Chemistry, North Dakota State University, Fargo 58105.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8085153" target="_blank"〉PubMed〈/a〉

    Description: The crystal structure of Thermus thermophilus seryl-transfer RNA synthetase, a class 2 aminoacyl-tRNA synthetase, complexed with a single tRNA(Ser) molecule was solved at 2.9 A resolution. The structure revealed how insertion of conserved base G20b from the D loop into the core of the tRNA determines the orientation of the long variable arm, which is a characteristic feature of most serine specific tRNAs. On tRNA binding, the antiparallel coiled-coil domain of one subunit of the synthetase makes contacts with the variable arm and T psi C loop of the tRNA and directs the acceptor stem of the tRNA into the active site of the other subunit. Specificity depends principally on recognition of the shape of tRNA(Ser) through backbone contacts and secondarily on sequence specific interactions.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Biou, V -- Yaremchuk, A -- Tukalo, M -- Cusack, S -- New York, N.Y. -- Science. 1994 Mar 11;263(5152):1404-10.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉European Molecular Biology Laboratory, Grenoble Outstation, France.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8128220" target="_blank"〉PubMed〈/a〉

    Description: The three-dimensional structure of a member of the beta subfamily of chemokines, human macrophage inflammatory protein-1 beta (hMIP-1 beta), has been determined with the use of solution multidimensional heteronuclear magnetic resonance spectroscopy. Human MIP-1 beta is a symmetric homodimer with a relative molecular mass of approximately 16 kilodaltons. The structure of the hMIP-1 beta monomer is similar to that of the related alpha chemokine interleukin-8 (IL-8). However, the quaternary structures of the two proteins are entirely distinct, and the dimer interface is formed by a completely different set of residues. Whereas the IL-8 dimer is globular, the hMIP-1 beta dimer is elongated and cylindrical. This provides a rational explanation for the absence of cross-binding and reactivity between the alpha and beta chemokine subfamilies. Calculation of the solvation free energies of dimerization suggests that the formation and stabilization of the two different types of dimers arise from the burial of hydrophobic residues.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lodi, P J -- Garrett, D S -- Kuszewski, J -- Tsang, M L -- Weatherbee, J A -- Leonard, W J -- Gronenborn, A M -- Clore, G M -- New York, N.Y. -- Science. 1994 Mar 25;263(5154):1762-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory of Chemical Physics, National Institute of Diabetes and Digestive and Kidney Diseases, National Institutes of Health, Bethesda, MD 20892.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8134838" target="_blank"〉PubMed〈/a〉

    Description: Plants contain most of the growth hormone indole-3-acetic acid (IAA) in conjugated forms believed to be inactive in promoting growth. The iaglu gene, which controls the first step in the biosynthesis of the IAA conjugates of Zea mays, encodes (uridine 5'-diphosphate-glucose:indol-3-ylacetyl)-beta-D-glucosyl transferase. Protein synthesized by Escherichia coli that contained cloned 1-O-beta-D-indol-3-ylacetyl-glucose complementary DNA (cDNA) was catalytically active. The predicted amino acid sequence of the cDNA was confirmed by amino-terminal sequencing of the purified enzyme. Homologous nucleotide sequences were found in all plants tested. The blockage or enhancement of iaglu expression may permit regulation of plant growth.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Szerszen, J B -- Szczyglowski, K -- Bandurski, R S -- New York, N.Y. -- Science. 1994 Sep 16;265(5179):1699-701.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Botany and Plant Pathology, Michigan State University, East Lansing 48824.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8085154" target="_blank"〉PubMed〈/a〉

    Description: The radiosensitive mutant xrs-6, derived from Chinese hamster ovary cells, is defective in DNA double-strand break repair and in ability to undergo V(D)J recombination. The human XRCC5 DNA repair gene, which complements this mutant, is shown here through genetic and biochemical evidence to be the 80-kilodalton subunit of the Ku protein. Ku binds to free double-stranded DNA ends and is the DNA-binding component of the DNA-dependent protein kinase. Thus, the Ku protein is involved in DNA repair and in V(D)J recombination, and these results may also indicate a role for the Ku-DNA-dependent protein kinase complex in those same processes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Taccioli, G E -- Gottlieb, T M -- Blunt, T -- Priestley, A -- Demengeot, J -- Mizuta, R -- Lehmann, A R -- Alt, F W -- Jackson, S P -- Jeggo, P A -- AI 20047/AI/NIAID NIH HHS/ -- Wellcome Trust/United Kingdom -- New York, N.Y. -- Science. 1994 Sep 2;265(5177):1442-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute, Children's Hospital, Boston, MA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8073286" target="_blank"〉PubMed〈/a〉

    Description: A simple technique has been devised that allows the direct synthesis of native backbone proteins of moderate size. Chemoselective reaction of two unprotected peptide segments gives an initial thioester-linked species. Spontaneous rearrangement of this transient intermediate yields a full-length product with a native peptide bond at the ligation site. The utility of native chemical ligation was demonstrated by the one-step preparation of a cytokine containing multiple disulfides. The polypeptide ligation product was folded and oxidized to form the native disulfide-containing protein molecule. Native chemical ligation is an important step toward the general application of chemistry to proteins.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Dawson, P E -- Muir, T W -- Clark-Lewis, I -- Kent, S B -- GM 50969-01/GM/NIGMS NIH HHS/ -- GM48870-03/GM/NIGMS NIH HHS/ -- GM48897-01/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1994 Nov 4;266(5186):776-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Scripps Research Institute, La Jolla, CA 92037.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7973629" target="_blank"〉PubMed〈/a〉

    Description: Macrocyclic polyketides have been subjects of great interest in synthetic and biosynthetic chemistry because of their structural complexity and medicinal activities. With expression of the entire 6-deoxyerythronolide B synthase (DEBS) (10,283 amino acids) in a heterologous host, substantial quantities of 6-deoxyerythronolide B (6dEB), the aglycone of the macrolide antibiotic erythromycin, and 8,8a-deoxyoleandolide, a 14-membered lactone ring identical to 6dEB except for a methyl group side chain in place of an ethyl unit, were synthesized in Streptomyces coelicolor. The biosynthetic strategy utilizes a genetic approach that facilitates rapid structural manipulation of DEBS or other modular polyketide synthases (PKSs), including those found in actinomycetes with poorly developed genetic methods. From a technological viewpoint, this approach should allow the rational design of biosynthetic products and may eventually lead to the generation of diverse polyketide libraries by means of combinatorial cloning of naturally occurring and mutant PKS modules.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kao, C M -- Katz, L -- Khosla, C -- New York, N.Y. -- Science. 1994 Jul 22;265(5171):509-12.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Chemical Engineering, Stanford University, CA 94305-5025.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8036492" target="_blank"〉PubMed〈/a〉

    Description: During transcription elongation, three flexibly connected parts of RNA polymerase of Escherichia coli advance along the template so that the front-end domain is followed by the catalytic site which in turn is followed by the RNA product binding site. The advancing enzyme was found to maintain the same conformation throughout extended segments of the transcribed region. However, when the polymerase traveled across certain DNA sites that seemed to briefly anchor the front-end domain, cyclic shifting of the three parts, accompanied by buildup and relief of internal strain, was observed. Thus, elongation proceeded in alternating laps of monotonous and inchworm-like movement with the flexible RNA polymerase configuration being subject to direct sequence control.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Nudler, E -- Goldfarb, A -- Kashlev, M -- GM49242/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1994 Aug 5;265(5173):793-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Public Health Research Institute, New York, NY 10016.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8047884" target="_blank"〉PubMed〈/a〉

The National Institutes of Health have developed a number of parallel algorithms and techniques useful in determining biological structure and function. These applications include processing electron micrographs to determine the three-dimensional structure of viruses, calculating the solvent-accessible surface area of proteins to help predict the three-dimensional conformation of these molecules from their primary structures, and searching for homologous DNA or amino acid sequences in large biological databases. Timing results demonstrate substantial performance improvements with parallel implementations compared with conventional sequential systems.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Martino, R L -- Johnson, C A -- Suh, E B -- Trus, B L -- Yap, T K -- New York, N.Y. -- Science. 1994 Aug 12;265(5174):902-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Computational Bioscience and Engineering Laboratory, National Institutes of Health, Bethesda, MD 20892.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8052847" target="_blank"〉PubMed〈/a〉
