    Bioactive contaminants leach from disposable laboratory plasticware (2008)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2008-11-08
    Description: Disposable plasticware such as test tubes, pipette tips, and multiwell assay or culture plates are used routinely in most biological research laboratories. Manufacturing of plastics requires the inclusion of numerous chemicals to enhance stability, durability, and performance. Some lubricating (slip) agents, exemplified by oleamide, also occur endogenously in humans and are biologically active, and cationic biocides are included to prevent bacterial colonization of the plastic surface. We demonstrate that these manufacturing agents leach from laboratory plasticware into a standard aqueous buffer, dimethyl sulfoxide, and methanol and can have profound effects on proteins and thus on results from bioassays of protein function. These findings have far-reaching implications for the use of disposable plasticware in biological research.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉McDonald, G Reid -- Hudson, Alan L -- Dunn, Susan M J -- You, Haitao -- Baker, Glen B -- Whittal, Randy M -- Martin, Jonathan W -- Jha, Amitabh -- Edmondson, Dale E -- Holt, Andrew -- New York, N.Y. -- Science. 2008 Nov 7;322(5903):917. doi: 10.1126/science.1162395.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Pharmacology, University of Alberta, Edmonton, AB T6G 2B7, Canada.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18988846" target="_blank"〉PubMed〈/a〉

    De novo computational design of retro-aldol enzymes (2008)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2008-03-08
    Description: The creation of enzymes capable of catalyzing any desired chemical reaction is a grand challenge for computational protein design. Using new algorithms that rely on hashing techniques to construct active sites for multistep reactions, we designed retro-aldolases that use four different catalytic motifs to catalyze the breaking of a carbon-carbon bond in a nonnatural substrate. Of the 72 designs that were experimentally characterized, 32, spanning a range of protein folds, had detectable retro-aldolase activity. Designs that used an explicit water molecule to mediate proton shuffling were significantly more successful, with rate accelerations of up to four orders of magnitude and multiple turnovers, than those involving charged side-chain networks. The atomic accuracy of the design process was confirmed by the x-ray crystal structure of active designs embedded in two protein scaffolds, both of which were nearly superimposable on the design model.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3431203/" 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/PMC3431203/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Jiang, Lin -- Althoff, Eric A -- Clemente, Fernando R -- Doyle, Lindsey -- Rothlisberger, Daniela -- Zanghellini, Alexandre -- Gallaher, Jasmine L -- Betker, Jamie L -- Tanaka, Fujie -- Barbas, Carlos F 3rd -- Hilvert, Donald -- Houk, Kendall N -- Stoddard, Barry L -- Baker, David -- R01 CA097328/CA/NCI NIH HHS/ -- R01 GM049857/GM/NIGMS NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2008 Mar 7;319(5868):1387-91. doi: 10.1126/science.1152692.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biochemistry, University of Washington, Seattle, WA 98195, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18323453" target="_blank"〉PubMed〈/a〉

    An inhibitor of FtsZ with potent and selective anti-staphylococcal activity (2008)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2008-09-20
    Description: FtsZ is an essential bacterial guanosine triphosphatase and homolog of mammalian beta-tubulin that polymerizes and assembles into a ring to initiate cell division. We have created a class of small synthetic antibacterials, exemplified by PC190723, which inhibits FtsZ and prevents cell division. PC190723 has potent and selective in vitro bactericidal activity against staphylococci, including methicillin- and multi-drug-resistant Staphylococcus aureus. The putative inhibitor-binding site of PC190723 was mapped to a region of FtsZ that is analogous to the Taxol-binding site of tubulin. PC190723 was efficacious in an in vivo model of infection, curing mice infected with a lethal dose of S. aureus. The data validate FtsZ as a target for antibacterial intervention and identify PC190723 as suitable for optimization into a new anti-staphylococcal therapy.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Haydon, David J -- Stokes, Neil R -- Ure, Rebecca -- Galbraith, Greta -- Bennett, James M -- Brown, David R -- Baker, Patrick J -- Barynin, Vladimir V -- Rice, David W -- Sedelnikova, Sveta E -- Heal, Jonathan R -- Sheridan, Joseph M -- Aiwale, Sachin T -- Chauhan, Pramod K -- Srivastava, Anil -- Taneja, Amit -- Collins, Ian -- Errington, Jeff -- Czaplewski, Lloyd G -- Biotechnology and Biological Sciences Research Council/United Kingdom -- Wellcome Trust/United Kingdom -- New York, N.Y. -- Science. 2008 Sep 19;321(5896):1673-5. doi: 10.1126/science.1159961.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Prolysis, Begbroke Science Park, Oxfordshire OX5 1PF, UK.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18801997" target="_blank"〉PubMed〈/a〉

    Evolutionary origins for social vocalization in a vertebrate hindbrain-spinal compartment (2008)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2008-07-19
    Description: The macroevolutionary events leading to neural innovations for social communication, such as vocalization, are essentially unexplored. Many fish vocalize during female courtship and territorial defense, as do amphibians, birds, and mammals. Here, we map the neural circuitry for vocalization in larval fish and show that the vocal network develops in a segment-like region across the most caudal hindbrain and rostral spinal cord. Taxonomic analysis demonstrates a highly conserved pattern between fish and all major lineages of vocal tetrapods. We propose that the vocal basis for acoustic communication among vertebrates evolved from an ancestrally shared developmental compartment already present in the early fishes.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2582147/" 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/PMC2582147/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bass, Andrew H -- Gilland, Edwin H -- Baker, Robert -- R01 DC000092/DC/NIDCD NIH HHS/ -- R01 DC000092-33/DC/NIDCD NIH HHS/ -- New York, N.Y. -- Science. 2008 Jul 18;321(5887):417-21. doi: 10.1126/science.1157632.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Neurobiology and Behavior, Cornell University, Ithaca, NY 14853, USA. ahb3@cornell.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18635807" target="_blank"〉PubMed〈/a〉
