    Assembly of transcriptionally active RNA polymerase I initiation factor SL1 from recombinant subunits (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1994-12-23
    Description: Initiation of ribosomal RNA synthesis by RNA polymerase I requires the promoter selectivity factor SL1, which consists of the TATA-binding protein, TBP, and three associated factors, TAFIS 110, 63, and 48. Here the in vivo and in vitro assembly of functional SL1 complexes from recombinant TAFIS and TBP are reported. Complexes containing TBP and all three TAFIS were as active in supporting transcription from the human ribosomal RNA gene promoter as endogenous SL1, whereas partial complexes without TBP did not efficiently direct transcription in vitro. These results suggest that TAFIS 110, 63, and 48, together with TBP, are necessary and sufficient to reconstitute a transcriptionally active SL1 complex.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Zomerdijk, J C -- Beckmann, H -- Comai, L -- Tjian, R -- New York, N.Y. -- Science. 1994 Dec 23;266(5193):2015-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute, Department of Molecular and Cell Biology, University of California, Berkeley 94720-3204.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7801130" target="_blank"〉PubMed〈/a〉

    Trans-acting dosage effects on the expression of model gene systems in maize aneuploids (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1994-12-23
    Description: The reduction in vigor of aneuploids was classically thought to be due to the imbalance of gene products expressed from the varied chromosome relative to those from the remainder of the genome. In this study, the dosage of chromosomal segments was varied, but the transcript level of most genes encoded therein showed compensation for the number of copies of the gene. Genes whose dosage was not altered were affected by aneuploidy of unlinked chromosomal segments. The phenotypic effects of aneuploidy and of a substantial fraction of quantitative variation are hypothesized to be the consequence of an altered dosage-sensitive regulatory system.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Guo, M -- Birchler, J A -- New York, N.Y. -- Science. 1994 Dec 23;266(5193):1999-2002.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17836517" target="_blank"〉PubMed〈/a〉

    Crystal structure of the catalytic domain of HIV-1 integrase: similarity to other polynucleotidyl transferases (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1994-12-23
    Description: HIV integrase is the enzyme responsible for inserting the viral DNA into the host chromosome; it is essential for HIV replication. The crystal structure of the catalytically active core domain (residues 50 to 212) of HIV-1 integrase was determined at 2.5 A resolution. The central feature of the structure is a five-stranded beta sheet flanked by helical regions. The overall topology reveals that this domain of integrase belongs to a superfamily of polynucleotidyl transferases that includes ribonuclease H and the Holliday junction resolvase RuvC. The active site region is identified by the position of two of the conserved carboxylate residues essential for catalysis, which are located at similar positions in ribonuclease H. In the crystal, two molecules form a dimer with a extensive solvent-inaccessible interface of 1300 A2 per monomer.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Dyda, F -- Hickman, A B -- Jenkins, T M -- Engelman, A -- Craigie, R -- Davies, D R -- New York, N.Y. -- Science. 1994 Dec 23;266(5193):1981-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory of Molecular Biology, NIDDK, NIH, Bethesda, MD 20892-0560.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7801124" target="_blank"〉PubMed〈/a〉

    Fatty acylation of two internal lysine residues required for the toxic activity of Escherichia coli hemolysin (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1994-12-23
    Description: Hemolysin of Escherichia coli is activated by fatty acylation of the protoxin, directed by the putative acyl transferase HlyC and by acyl carrier protein (ACP). Mass spectrometry and Edman degradation of proteolytic products from mature toxin activated in vitro with tritium-labeled acylACP revealed two fatty-acylated internal lysine residues, lysine 564 and lysine 690. Resistance of the acylation to chemical treatments suggested that fatty acid was amide linked. Substitution of the two lysines confirmed that they were the only sites of acylation and showed that although each was acylated in the absence of the other, both sites were required for in vivo toxin activity.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Stanley, P -- Packman, L C -- Koronakis, V -- Hughes, C -- New York, N.Y. -- Science. 1994 Dec 23;266(5193):1992-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Pathology, Cambridge University, UK.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7801126" target="_blank"〉PubMed〈/a〉
