    Conserved folding in retroviral proteases: crystal structure of a synthetic HIV-1 protease (1989)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1989-08-11
    Beschreibung: The rational design of drugs that can inhibit the action of viral proteases depends on obtaining accurate structures of these enzymes. The crystal structure of chemically synthesized HIV-1 protease has been determined at 2.8 angstrom resolution (R factor of 0.184) with the use of a model based on the Rous sarcoma virus protease structure. In this enzymatically active protein, the cysteines were replaced by alpha-amino-n-butyric acid, a nongenetically coded amino acid. This structure, in which all 99 amino acids were located, differs in several important details from that reported previously by others. The interface between the identical subunits forming the active protease dimer is composed of four well-ordered beta strands from both the amino and carboxyl termini and residues 86 to 94 have a helical conformation. The observed arrangement of the dimer interface suggests possible designs for dimerization inhibitors.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wlodawer, A -- Miller, M -- Jaskolski, M -- Sathyanarayana, B K -- Baldwin, E -- Weber, I T -- Selk, L M -- Clawson, L -- Schneider, J -- Kent, S B -- N01-CO-74101/CO/NCI NIH HHS/ -- New York, N.Y. -- Science. 1989 Aug 11;245(4918):616-21.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Crystallography Laboratory, NCI-Frederick Cancer Research Facility, MD 21701.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2548279" target="_blank"〉PubMed〈/a〉

    From the genome to the proteome: uncovering peptides in the Apis brain (2006)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2006-10-28
    Beschreibung: Neuropeptides, critical brain peptides that modulate animal behavior by affecting the activity of almost every neuronal circuit, are inherently difficult to predict directly from a nascent genome sequence because of extensive posttranslational processing. The combination of bioinformatics and proteomics allows unprecedented neuropeptide discovery from an unannotated genome. Within the Apis mellifera genome, we have inferred more than 200 neuropeptides and have confirmed the sequences of 100 peptides. This study lays the groundwork for future molecular studies of Apis neuropeptides with the identification of 36 genes, 33 of which were previously unreported.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hummon, Amanda B -- Richmond, Timothy A -- Verleyen, Peter -- Baggerman, Geert -- Huybrechts, Jurgen -- Ewing, Michael A -- Vierstraete, Evy -- Rodriguez-Zas, Sandra L -- Schoofs, Liliane -- Robinson, Gene E -- Sweedler, Jonathan V -- DC006395/DC/NIDCD NIH HHS/ -- GM068946/GM/NIGMS NIH HHS/ -- NS31609/NS/NINDS NIH HHS/ -- P30 DA01830/DA/NIDA NIH HHS/ -- P30 DA018310/DA/NIDA NIH HHS/ -- R01 GM068946/GM/NIGMS NIH HHS/ -- R01 NS031609/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 2006 Oct 27;314(5799):647-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Chemistry, University of Illinois, Urbana, IL 61801, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17068263" target="_blank"〉PubMed〈/a〉

    Identification of the fusion peptide of primate immunodeficiency viruses (1989)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1989-05-12
    Beschreibung: Membrane fusion induced by the envelope glycoproteins of human and simian immunodeficiency viruses (HIV and SIVmac) is a necessary step for the infection of CD4 cells and for the formation of syncytia after infection. Identification of the region in these molecules that mediates the fusion events is important for understanding and possibly interfering with HIV/SIVmac infection and pathogenesis. Amino acid substitutions were made in the 15 NH2-terminal residues of the SIVmac gp32 transmembrane glycoprotein, and the mutants were expressed in recombinant vaccinia viruses, which were then used to infect CD4-expressing T cell lines. Mutations that increased the overall hydrophobicity of the gp32 NH2-terminus increased the ability of the viral envelope to induce syncytia formation, whereas introduction of polar or charged amino acids in the same region abolished the fusogenic function of the viral envelope. Hydrophobicity in the NH2-terminal region of gp32 may therefore be an important correlate of viral virulence in vivo and could perhaps be exploited to generate a more effective animal model for the study of acquired immunodeficiency syndrome.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bosch, M L -- Earl, P L -- Fargnoli, K -- Picciafuoco, S -- Giombini, F -- Wong-Staal, F -- Franchini, G -- New York, N.Y. -- Science. 1989 May 12;244(4905):694-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory of Tumor Cell Biology, National Cancer Institute, Bethesda, MD 20892.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2541505" target="_blank"〉PubMed〈/a〉

    Cloning and expression of a Xenopus embryonic gap junction protein (1989)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1989-03-03
    Beschreibung: Gap junctions in the early amphibian embryo may play a fundamental role in the regulation of differentiation by mediating the cell-to-cell transfer of chemical signals. A complementary DNA encoding a gap junction present in Xenopus oocytes and early embryos has now been cloned and sequenced. This protein sequence is homologous to the well-characterized gap junction structural proteins rat connexin32 and connexin43. RNA blot analysis of total Xenopus oocyte RNA showed hybridization to a single 1.6-kilobase band. This messenger RNA is abundant in oocytes, decreases to levels below the sensitivity of our assay by stage 15 (18 hours), and is not detectable in RNA from a number of adult organs. To confirm that the oocyte cDNA encodes a gap junction channel, the protein was over expressed in Xenopus oocytes by injection of RNA synthesized in vitro. Pairs of RNA-injected oocytes formed many more time- and voltage-sensitive cell-cell channels than water-injected pairs.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ebihara, L -- Beyer, E C -- Swenson, K I -- Paul, D L -- Goodenough, D A -- GM18974/GM/NIGMS NIH HHS/ -- GM37751/GM/NIGMS NIH HHS/ -- HL28958-06/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 1989 Mar 3;243(4895):1194-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Pharmacology, Columbia University, New York, NY 10032.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2466337" target="_blank"〉PubMed〈/a〉

    A secreted serine-threonine kinase determines virulence in the eukaryotic pathogen Toxoplasma gondii (2006)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2006-12-16
    Beschreibung: Toxoplasma gondii strains differ dramatically in virulence despite being genetically very similar. Genetic mapping revealed two closely adjacent quantitative trait loci on parasite chromosome VIIa that control the extreme virulence of the type I lineage. Positional cloning identified the candidate virulence gene ROP18, a highly polymorphic serine-threonine kinase that was secreted into the host cell during parasite invasion. Transfection of the virulent ROP18 allele into a nonpathogenic type III strain increased growth and enhanced mortality by 4 to 5 logs. These attributes of ROP18 required kinase activity, which revealed that secretion of effectors is a major component of parasite virulence.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Taylor, S -- Barragan, A -- Su, C -- Fux, B -- Fentress, S J -- Tang, K -- Beatty, W L -- Hajj, H El -- Jerome, M -- Behnke, M S -- White, M -- Wootton, J C -- Sibley, L D -- AI059176/AI/NIAID NIH HHS/ -- AI36629/AI/NIAID NIH HHS/ -- AI44600/AI/NIAID NIH HHS/ -- P20 RR-020185/RR/NCRR NIH HHS/ -- Intramural NIH HHS/ -- New York, N.Y. -- Science. 2006 Dec 15;314(5806):1776-80.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular Microbiology, Washington University School of Medicine, St. Louis, MO 63130, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17170305" target="_blank"〉PubMed〈/a〉

    Structure of the exon junction core complex with a trapped DEAD-box ATPase bound to RNA (2006)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2006-08-26
    Beschreibung: In higher eukaryotes, a multiprotein exon junction complex is deposited on spliced messenger RNAs. The complex is organized around a stable core, which serves as a binding platform for numerous factors that influence messenger RNA function. Here, we present the crystal structure of a tetrameric exon junction core complex containing the DEAD-box adenosine triphosphatase (ATPase) eukaryotic initiation factor 4AIII (eIF4AIII) bound to an ATP analog, MAGOH, Y14, a fragment of MLN51, and a polyuracil mRNA mimic. eIF4AIII interacts with the phosphate-ribose backbone of six consecutive nucleotides and prevents part of the bound RNA from being double stranded. The MAGOH and Y14 subunits lock eIF4AIII in a prehydrolysis state, and activation of the ATPase probably requires only modest conformational changes in eIF4AIII motif I.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Andersen, Christian B F -- Ballut, Lionel -- Johansen, Jesper S -- Chamieh, Hala -- Nielsen, Klaus H -- Oliveira, Cristiano L P -- Pedersen, Jan Skov -- Seraphin, Bertrand -- Le Hir, Herve -- Andersen, Gregers Rom -- New York, N.Y. -- Science. 2006 Sep 29;313(5795):1968-72.

    A gain-of-function mutation in a cytokinin receptor triggers spontaneous root nodule organogenesis (2006)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2006-11-18
    Beschreibung: Legume root nodules originate from differentiated cortical cells that reenter the cell cycle and form organ primordia. We show that perception of the phytohormone cytokinin is a key element in this switch. Mutation of a Lotus japonicus cytokinin receptor gene leads to spontaneous development of root nodules in the absence of rhizobia or rhizobial signal molecules. The mutant histidine kinase receptor has cytokinin-independent activity and activates an Escherichia coli two-component phosphorelay system in vivo. Mutant analysis shows that cytokinin signaling is required for cell divisions that initiate nodule development and defines an autoregulated process where cytokinin induction of nodule stem cells is controlled by shoots.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Tirichine, Leila -- Sandal, Niels -- Madsen, Lene H -- Radutoiu, Simona -- Albrektsen, Anita S -- Sato, Shusei -- Asamizu, Erika -- Tabata, Satoshi -- Stougaard, Jens -- New York, N.Y. -- Science. 2007 Jan 5;315(5808):104-7.

The system allows rapid and easy identification of monoclonal Fab fragments in a form suitable for genetic manipulation. It was possible to generate, in 2 weeks, large numbers of monoclonal Fab fragments against a transition state analog hapten.

    Sequence-specific peptide cleavage catalyzed by an antibody (1989)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1989-03-03
    Beschreibung: Monoclonal antibodies have been induced that are capable of catalyzing specific hydrolysis of the Gly-Phe bond of peptide substrates at neutral pH with a metal complex cofactor. The antibodies were produced by immunizing with a Co(III) triethylenetetramine (trien)-peptide hapten. These antibodies as a group are capable of binding trien complexes of not only Co(III) but also of numerous other metals. Six peptides were examined as possible substrates with the antibodies and various metal complexes. Two of these peptides were cleaved by several of the antibodies. One antibody was studied in detail, and cleavage was observed for the substrates with the trien complexes of Zn(II), Ga(III), Fe(III), In(III), Cu(II), Ni(II), Lu(III), Mg(II), or Mn(II) as cofactors. A turnover number of 6 x 10(-4) per second was observed for these substrates. These results demonstrate the feasibility of the use of cofactor-assisted catalysis in an antibody binding site to accomplish difficult chemical transformations.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Iverson, B L -- Lerner, R A -- New York, N.Y. -- Science. 1989 Mar 3;243(4895):1184-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular Biology, Research Institute of Scripps Clinic, La Jolla, CA 92037.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2922606" target="_blank"〉PubMed〈/a〉

    Peptide and protein synthesis by segment synthesis-condensation (1989)

    Details
    Publikationsdatum: 1989-01-13
    Beschreibung: The chemical synthesis of biologically active peptides and polypeptides can be achieved by using a convergent strategy of condensing protected peptide segments to form the desired molecule. An oxime support increases the ease with which intermediate protected peptides can be synthesized and makes this approach useful for the synthesis of peptides in which secondary structural elements have been redesigned. The extension of these methods to large peptides and proteins, for which folding of secondary structures into functional tertiary structures is critical, is discussed. Models of apolipoproteins, the homeo domain from the developmental protein encoded by the Antennapedia gene of Drosophila, a part of the Cro repressor, and the enzyme ribonuclease T1 and a structural analog have been synthesized with this method.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kaiser, E T -- Mihara, H -- Laforet, G A -- Kelly, J W -- Walters, L -- Findeis, M A -- Sasaki, T -- DK07825/DK/NIDDK NIH HHS/ -- GM12054/GM/NIGMS NIH HHS/ -- HL-186577/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 1989 Jan 13;243(4888):187-92.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory of Bioorganic Chemistry and Biochemistry, Rockefeller University, New York, NY 10021.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2492114" target="_blank"〉PubMed〈/a〉
