    Derivatives of erythropoietin that are tissue protective but not erythropoietic (2004)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2004-07-13
    Description: Erythropoietin (EPO) is both hematopoietic and tissue protective, putatively through interaction with different receptors. We generated receptor subtype-selective ligands allowing the separation of EPO's bioactivities at the cellular level and in animals. Carbamylated EPO (CEPO) or certain EPO mutants did not bind to the classical EPO receptor (EPOR) and did not show any hematopoietic activity in human cell signaling assays or upon chronic dosing in different animal species. Nevertheless, CEPO and various nonhematopoietic mutants were cytoprotective in vitro and conferred neuroprotection against stroke, spinal cord compression, diabetic neuropathy, and experimental autoimmune encephalomyelitis at a potency and efficacy comparable to EPO.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Leist, Marcel -- Ghezzi, Pietro -- Grasso, Giovanni -- Bianchi, Roberto -- Villa, Pia -- Fratelli, Maddalena -- Savino, Costanza -- Bianchi, Marina -- Nielsen, Jacob -- Gerwien, Jens -- Kallunki, Pekka -- Larsen, Anna Kirstine -- Helboe, Lone -- Christensen, Soren -- Pedersen, Lars O -- Nielsen, Mette -- Torup, Lars -- Sager, Thomas -- Sfacteria, Alessandra -- Erbayraktar, Serhat -- Erbayraktar, Zubeyde -- Gokmen, Necati -- Yilmaz, Osman -- Cerami-Hand, Carla -- Xie, Qiao-Wen -- Coleman, Thomas -- Cerami, Anthony -- Brines, Michael -- New York, N.Y. -- Science. 2004 Jul 9;305(5681):239-42.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉H.

    Structure of the allosteric regulatory enzyme of purine biosynthesis (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1994-06-03
    Description: Multi-wavelength anomalous diffraction (MAD) has been used to determine the structure of the regulatory enzyme of de novo synthesis of purine nucleotides, glutamine 5-phosphoribosyl-1-pyrophosphate (PRPP) amidotransferase, from Bacillus subtilis. This allosteric enzyme, a 200-kilodalton tetramer, is subject to end product regulation by purine nucleotides. The metalloenzyme from B. subtilis is a paradigm for the higher eukaryotic enzymes, which have been refractory to isolation in stable form. The two folding domains of the polypeptide are correlated with functional domains for glutamine binding and for transfer of ammonia to the substrate PRPP. Eight molecules of the feedback inhibitor adenosine monophosphate (AMP) are bound to the tetrameric enzyme in two types of binding sites: the PRPP catalytic site of each subunit and an unusual regulatory site that is immediately adjacent to each active site but is between subunits. An oxygen-sensitive [4Fe-4S] cluster in each subunit is proposed to regulate protein turnover in vivo and is distant from the catalytic site. Oxygen sensitivity of the cluster is diminished by AMP, which blocks a channel through the protein to the cluster. The structure is representative of both glutamine amidotransferases and phosphoribosyltransferases.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Smith, J L -- Zaluzec, E J -- Wery, J P -- Niu, L -- Switzer, R L -- Zalkin, H -- Satow, Y -- DK-42303/DK/NIDDK NIH HHS/ -- GM-24658/GM/NIGMS NIH HHS/ -- R37 DK042303/DK/NIDDK NIH HHS/ -- New York, N.Y. -- Science. 1994 Jun 3;264(5164):1427-33.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biological Sciences, Purdue University, West Lafayette, IN 47907.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8197456" target="_blank"〉PubMed〈/a〉

    Cytochrome b558: the flavin-binding component of the phagocyte NADPH oxidase (1992)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1992-06-05
    Description: The phagocyte respiratory burst oxidase is a flavin-adenine dinucleotide (FAD)-dependent dehydrogenase and an electron transferase that reduces molecular oxygen to superoxide anion, a precursor of microbicidal oxidants. Several proteins required for assembly of the oxidase have been characterized, but the identity of its flavin-binding component has been unclear. Oxidase activity was reconstituted in vitro with only the purified oxidase proteins p47phox, p67phox, Rac-related guanine nucleotide (GTP)-binding proteins, and membrane-bound cytochrome b558. The reconstituted oxidase required added FAD, and FAD binding was localized to cytochrome b558. Alignment of the amino acid sequence of the beta subunit of cytochrome b558 (gp91phox) with other flavoproteins revealed similarities to the nicotinamide adenine dinucleotide phosphate (reduced) (NADPH)-binding domains. Thus flavocytochrome b558 is the only obligate electron transporting component of the NADPH oxidase.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rotrosen, D -- Yeung, C L -- Leto, T L -- Malech, H L -- Kwong, C H -- New York, N.Y. -- Science. 1992 Jun 5;256(5062):1459-62.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory of Host Defenses, National Institute of Allergy and Infectious 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/1318579" target="_blank"〉PubMed〈/a〉

    A domain in TNF receptors that mediates ligand-independent receptor assembly and signaling (2000)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2000-07-06
    Description: A conserved domain in the extracellular region of the 60- and 80-kilodalton tumor necrosis factor receptors (TNFRs) was identified that mediates specific ligand-independent assembly of receptor trimers. This pre-ligand-binding assembly domain (PLAD) is physically distinct from the domain that forms the major contacts with ligand, but is necessary and sufficient for the assembly of TNFR complexes that bind TNF-alpha and mediate signaling. Other members of the TNFR superfamily, including TRAIL receptor 1 and CD40, show similar homotypic association. Thus, TNFRs and related receptors appear to function as preformed complexes rather than as individual receptor subunits that oligomerize after ligand binding.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chan, F K -- Chun, H J -- Zheng, L -- Siegel, R M -- Bui, K L -- Lenardo, M J -- New York, N.Y. -- Science. 2000 Jun 30;288(5475):2351-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory of Immunology, National Institute of Allergy and Infectious Diseases, National Institutes of Health, Bethesda, MD 20892, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10875917" target="_blank"〉PubMed〈/a〉

    Chemical glycobiology (2001)

    Details
    Publication Date: 2001-03-28
    Description: Chemical tools have proven indispensable for studies in glycobiology. Synthetic oligosaccharides and glycoconjugates provide materials for correlating structure with function. Synthetic mimics of the complex assemblies found on cell surfaces can modulate cellular interactions and are under development as therapeutic agents. Small molecule inhibitors of carbohydrate biosynthetic and processing enzymes can block the assembly of specific oligosaccharide structures. Inhibitors of carbohydrate recognition and biosynthesis can reveal the biological functions of the carbohydrate epitope and its cognate receptors. Carbohydrate biosynthetic pathways are often amenable to interception with synthetic unnatural substrates. Such metabolic interference can block the expression of oligosaccharides or alter the structures of the sugars presented on cells. Collectively, these chemical approaches are contributing great insight into the myriad biological functions of oligosaccharides.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bertozzi, C R -- Kiessling, L L -- New York, N.Y. -- Science. 2001 Mar 23;291(5512):2357-64.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Departments of Chemistry and Molecular and Cell Biology and Howard Hughes Medical Institute, University of California, Berkeley, CA 94720, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/11269316" target="_blank"〉PubMed〈/a〉

    Crystal structure of the extracellular segment of integrin alpha Vbeta3 (2001)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2001-09-08
    Description: Integrins are alphabeta heterodimeric receptors that mediate divalent cation-dependent cell-cell and cell-matrix adhesion through tightly regulated interactions with ligands. We have solved the crystal structure of the extracellular portion of integrin alphaVbeta3 at 3.1 A resolution. Its 12 domains assemble into an ovoid "head" and two "tails." In the crystal, alphaVbeta3 is severely bent at a defined region in its tails, reflecting an unusual flexibility that may be linked to integrin regulation. The main inter-subunit interface lies within the head, between a seven-bladed beta-propeller from alphaV and an A domain from beta3, and bears a striking resemblance to the Galpha/Gbeta interface in G proteins. A metal ion-dependent adhesion site (MIDAS) in the betaA domain is positioned to participate in a ligand-binding interface formed of loops from the propeller and betaA domains. MIDAS lies adjacent to a calcium-binding site with a potential regulatory function.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2885948/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2885948/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Xiong, J P -- Stehle, T -- Diefenbach, B -- Zhang, R -- Dunker, R -- Scott, D L -- Joachimiak, A -- Goodman, S L -- Arnaout, M A -- AI45716/AI/NIAID NIH HHS/ -- DK48549/DK/NIDDK NIH HHS/ -- DK50305/DK/NIDDK NIH HHS/ -- HL54227/HL/NHLBI NIH HHS/ -- P50 GM062414/GM/NIGMS NIH HHS/ -- P50 GM062414-02/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2001 Oct 12;294(5541):339-45.

    An hPer2 phosphorylation site mutation in familial advanced sleep phase syndrome (2001)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2001-03-10
    Description: Familial advanced sleep phase syndrome (FASPS) is an autosomal dominant circadian rhythm variant; affected individuals are "morning larks" with a 4-hour advance of the sleep, temperature, and melatonin rhythms. Here we report localization of the FASPS gene near the telomere of chromosome 2q. A strong candidate gene (hPer2), a human homolog of the period gene in Drosophila, maps to the same locus. Affected individuals have a serine to glycine mutation within the casein kinase Iepsilon (CKIepsilon) binding region of hPER2, which causes hypophosphorylation by CKIepsilon in vitro. Thus, a variant in human sleep behavior can be attributed to a missense mutation in a clock component, hPER2, which alters the circadian period.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Toh, K L -- Jones, C R -- He, Y -- Eide, E J -- Hinz, W A -- Virshup, D M -- Ptacek, L J -- Fu, Y H -- HL/HD 59596/HL/NHLBI NIH HHS/ -- M01-RR00064/RR/NCRR NIH HHS/ -- New York, N.Y. -- Science. 2001 Feb 9;291(5506):1040-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Human Genetics, University of Utah, Salt Lake City, UT 84112, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/11232563" target="_blank"〉PubMed〈/a〉

    Enlarging the amino acid set of Escherichia coli by infiltration of the valine coding pathway (2001)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2001-04-21
    Description: Aminoacyl transfer RNA (tRNA) synthetases establish the rules of the genetic code by catalyzing the aminoacylation of tRNAs. For some synthetases, accuracy depends critically on an editing function at a site distinct from the aminoacylation site. Mutants of Escherichia coli that incorrectly charge tRNA(Val) with cysteine were selected after random mutagenesis of the whole chromosome. All mutations obtained were located in the editing site of valyl-tRNA synthetase. More than 20% of the valine in cellular proteins from such an editing mutant organism could be replaced with the noncanonical aminobutyrate, sterically similar to cysteine. Thus, the editing function may have played a central role in restricting the genetic code to 20 amino acids. Disabling this editing function offers a powerful approach for diversifying the chemical composition of proteins and for emulating evolutionary stages of ambiguous translation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Doring, V -- Mootz, H D -- Nangle, L A -- Hendrickson, T L -- de Crecy-Lagard, V -- Schimmel, P -- Marliere, P -- GM23562/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2001 Apr 20;292(5516):501-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Evologic SA, 4 rue Pierre Fontaine, 91000 Evry, France.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/11313495" target="_blank"〉PubMed〈/a〉

    The human nuclear xenobiotic receptor PXR: structural determinants of directed promiscuity (2001)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2001-06-16
    Description: The human nuclear pregnane X receptor (hPXR) activates cytochrome P450-3A expression in response to a wide variety of xenobiotics and plays a critical role in mediating dangerous drug-drug interactions. We present the crystal structures of the ligand-binding domain of hPXR both alone and in complex with the cholesterol-lowering drug SR12813 at resolutions of 2.5 and 2.75 angstroms, respectively. The hydrophobic ligand-binding cavity of hPXR contains a small number of polar residues, permitting SR12813 to bind in three distinct orientations. The position and nature of these polar residues were found to be critical for establishing the precise pharmacologic activation profile of PXR. Our findings provide important insights into how hPXR detects xenobiotics and may prove useful in predicting and avoiding drug-drug interactions.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Watkins, R E -- Wisely, G B -- Moore, L B -- Collins, J L -- Lambert, M H -- Williams, S P -- Willson, T M -- Kliewer, S A -- Redinbo, M R -- New York, N.Y. -- Science. 2001 Jun 22;292(5525):2329-33.

    No specific recognition of leader peptide by SecB, a chaperone involved in protein export (1990)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1990-05-18
    Description: Most proteins destined for export from Escherichia coli are made as precursors containing amino-terminal leader sequences that are essential for export and that are removed during the process. The initial step in export of a subset of proteins, which includes maltose-binding protein, is binding of the precursor by the molecular chaperone SecB. This work shows directly that SecB binds with high affinity to unfolded maltose-binding protein but does not specifically recognize and bind the leader. Rather, the leader modulates folding to expose elements in the remainder of the polypeptide that are recognized by SecB.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Randall, L L -- Topping, T B -- Hardy, S J -- GM 29798/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1990 May 18;248(4957):860-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Biochemistry/Biophysics Program, Washington State University, Pullman 99164-4660.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2188362" target="_blank"〉PubMed〈/a〉
