    Evidence from 18S ribosomal RNA sequences that lampreys and hagfishes form a natural group (1992)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1992-08-07
    Beschreibung: Lampreys and hagfishes (cyclostomes) traditionally were considered to be a natural (monophyletic) group. Recently, the consensus of opinion, based largely on morphological analyses, has shifted to a view that lampreys are more closely related to jawed vertebrates (gnathostomes) than to hagfishes. Phylogenetic comparisons of 18S ribosomal RNA sequences from two hagfishes, two lampreys, a tunicate, a lancelet, and a number of gnathostomes support the monophyly of the cyclostomes. These data force a reassessment of several features of early vertebrate evolution.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Stock, D W -- Whitt, G S -- New York, N.Y. -- Science. 1992 Aug 7;257(5071):787-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Ecology, Ethology, and Evolution, University of Illinois, Urbana 61801.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1496398" target="_blank"〉PubMed〈/a〉

    Crystal structure of the 20S proteasome from the archaeon T. acidophilum at 3.4 A resolution (1995)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1995-04-28
    Beschreibung: The three-dimensional structure of the proteasome from the archaebacterium Thermoplasma acidophilum has been elucidated by x-ray crystallographic analysis by means of isomorphous replacement and cyclic averaging. The atomic model was built and refined to a crystallographic R factor of 22.1 percent. The 673-kilodalton protease complex consists of 14 copies of two different subunits, alpha and beta, forming a barrel-shaped structure of four stacked rings. The two inner rings consist of seven beta subunits each, and the two outer rings consist of seven alpha subunits each. A narrow channel controls access to the three inner compartments. The alpha 7 beta 7 beta 7 alpha 7 subunit assembly has 72-point group symmetry. The structures of the alpha and beta subunits are similar, consisting of a core of two antiparallel beta sheets that is flanked by alpha helices on both sides. The binding of a peptide aldehyde inhibitor marks the active site in the central cavity at the amino termini of the beta subunits and suggests a novel proteolytic mechanism.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lowe, J -- Stock, D -- Jap, B -- Zwickl, P -- Baumeister, W -- Huber, R -- New York, N.Y. -- Science. 1995 Apr 28;268(5210):533-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Max-Planck-Institut fur Biochemie, Abteilung fur Strukturforschung, Martinsried, Germany.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7725097" target="_blank"〉PubMed〈/a〉

    Proteasome from Thermoplasma acidophilum: a threonine protease (1995)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1995-04-28
    Beschreibung: The catalytic mechanism of the 20S proteasome from the archaebacterium Thermoplasma acidophilum has been analyzed by site-directed mutagenesis of the beta subunit and by inhibitor studies. Deletion of the amino-terminal threonine or its mutation to alanine led to inactivation of the enzyme. Mutation of the residue to serine led to a fully active enzyme, which was over ten times more sensitive to the serine protease inhibitor 3,4-dichloroisocoumarin. In combination with the crystal structure of a proteasome-inhibitor complex, the data show that the nucleophilic attack is mediated by the amino-terminal threonine of processed beta subunits. The conservation pattern of this residue in eukaryotic sequences suggests that at least three of the seven eukaryotic beta-type subunit branches should be proteolytically inactive.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Seemuller, E -- Lupas, A -- Stock, D -- Lowe, J -- Huber, R -- Baumeister, W -- New York, N.Y. -- Science. 1995 Apr 28;268(5210):579-82.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Abteilung fur Strukturbiologie Max-Planck Institut fur Biochemie, Martinsried, Germany.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7725107" target="_blank"〉PubMed〈/a〉
