    The after-hours mutant reveals a role for Fbxl3 in determining mammalian circadian period (2007)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2007-04-28
    Description: By screening N-ethyl-N-nitrosourea-mutagenized animals for alterations in rhythms of wheel-running activity, we identified a mouse mutation, after hours (Afh). The mutation, a Cys(358)Ser substitution in Fbxl3, an F-box protein with leucine-rich repeats, results in long free-running rhythms of about 27 hours in homozygotes. Circadian transcriptional and translational oscillations are attenuated in Afh mice. The Afh allele significantly affected Per2 expression and delayed the rate of Cry protein degradation in Per2::Luciferase tissue slices. Our in vivo and in vitro studies reveal a central role for Fbxl3 in mammalian circadian timekeeping.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Godinho, Sofia I H -- Maywood, Elizabeth S -- Shaw, Linda -- Tucci, Valter -- Barnard, Alun R -- Busino, Luca -- Pagano, Michele -- Kendall, Rachel -- Quwailid, Mohamed M -- Romero, M Rosario -- O'neill, John -- Chesham, Johanna E -- Brooker, Debra -- Lalanne, Zuzanna -- Hastings, Michael H -- Nolan, Patrick M -- MC_U105170643/Medical Research Council/United Kingdom -- MC_U142684172/Medical Research Council/United Kingdom -- MC_U142684173/Medical Research Council/United Kingdom -- MC_U142684175/Medical Research Council/United Kingdom -- New York, N.Y. -- Science. 2007 May 11;316(5826):897-900.

    Structural insight into the transglycosylation step of bacterial cell-wall biosynthesis (2007)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2007-03-10
    Description: Peptidoglycan glycosyltransferases (GTs) catalyze the polymerization step of cell-wall biosynthesis, are membrane-bound, and are highly conserved across all bacteria. Long considered the "holy grail" of antibiotic research, they represent an essential and easily accessible drug target for antibiotic-resistant bacteria, including methicillin-resistant Staphylococcus aureus. We have determined the 2.8 angstrom structure of a bifunctional cell-wall cross-linking enzyme, including its transpeptidase and GT domains, both unliganded and complexed with the substrate analog moenomycin. The peptidoglycan GTs adopt a fold distinct from those of other GT classes. The structures give insight into critical features of the catalytic mechanism and key interactions required for enzyme inhibition.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lovering, Andrew L -- de Castro, Liza H -- Lim, Daniel -- Strynadka, Natalie C J -- New York, N.Y. -- Science. 2007 Mar 9;315(5817):1402-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biochemistry and Molecular Biology, and Center for Blood Research, University of British Columbia, 2350 Health Sciences Mall, Vancouver, Canada.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17347437" target="_blank"〉PubMed〈/a〉

    Structural and regulatory genes required to make the gas dimethyl sulfide in bacteria (2007)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2007-02-03
    Description: Dimethyl sulfide (DMS) is a key compound in global sulfur and carbon cycles. DMS oxidation products cause cloud nucleation and may affect weather and climate. DMS is generated largely by bacterial catabolism of dimethylsulfoniopropionate (DMSP), a secondary metabolite made by marine algae. We demonstrate that the bacterial gene dddD is required for this process and that its transcription is induced by the DMSP substrate. Cloned dddD from the marine bacterium Marinomonas and from two bacterial strains that associate with higher plants, the N(2)-fixing symbiont Rhizobium NGR234 and the root-colonizing Burkholderia cepacia AMMD, conferred to Escherichia coli the ability to make DMS from DMSP. The inferred enzymatic mechanism for DMS liberation involves an initial step in which DMSP is modified by addition of acyl coenzyme A, rather than the immediate release of DMS by a DMSP lyase, the previously suggested mechanism.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Todd, Jonathan D -- Rogers, Rachel -- Li, You Guo -- Wexler, Margaret -- Bond, Philip L -- Sun, Lei -- Curson, Andrew R J -- Malin, Gill -- Steinke, Michael -- Johnston, Andrew W B -- New York, N.Y. -- Science. 2007 Feb 2;315(5812):666-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉School of Biological Sciences, University of East Anglia, Norwich Research Park, Norwich NR4 7TJ, UK.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17272727" target="_blank"〉PubMed〈/a〉

    Protein sequences from mastodon and Tyrannosaurus rex revealed by mass spectrometry (2007)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2007-04-14
    Description: Fossilized bones from extinct taxa harbor the potential for obtaining protein or DNA sequences that could reveal evolutionary links to extant species. We used mass spectrometry to obtain protein sequences from bones of a 160,000- to 600,000-year-old extinct mastodon (Mammut americanum) and a 68-million-year-old dinosaur (Tyrannosaurus rex). The presence of T. rex sequences indicates that their peptide bonds were remarkably stable. Mass spectrometry can thus be used to determine unique sequences from ancient organisms from peptide fragmentation patterns, a valuable tool to study the evolution and adaptation of ancient taxa from which genomic sequences are unlikely to be obtained.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Asara, John M -- Schweitzer, Mary H -- Freimark, Lisa M -- Phillips, Matthew -- Cantley, Lewis C -- New York, N.Y. -- Science. 2007 Apr 13;316(5822):280-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Signal Transduction, Beth Israel Deaconess Medical Center, Boston, MA 02115, USA. jasara@bidmc.harvard.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17431180" target="_blank"〉PubMed〈/a〉

    An ancient mechanism controls the development of cells with a rooting function in land plants (2007)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2007-06-09
    Description: Root hairs and rhizoids are cells with rooting functions in land plants. We describe two basic helix-loop-helix transcription factors that control root hair development in the sporophyte (2n) of the angiosperm Arabidopsis thaliana and rhizoid development in the gametophytes (n) of the bryophyte Physcomitrella patens. The phylogeny of land plants supports the hypothesis that early land plants were bryophyte-like and possessed a dominant gametophyte and later the sporophyte rose to dominance. If this hypothesis is correct, our data suggest that the increase in morphological complexity of the sporophyte body in the Paleozoic resulted at least in part from the recruitment of regulatory genes from gametophyte to sporophyte.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Menand, Benoit -- Yi, Keke -- Jouannic, Stefan -- Hoffmann, Laurent -- Ryan, Eoin -- Linstead, Paul -- Schaefer, Didier G -- Dolan, Liam -- BBS/E/J/0000A218/Biotechnology and Biological Sciences Research Council/United Kingdom -- New York, N.Y. -- Science. 2007 Jun 8;316(5830):1477-80.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Cell and Developmental Biology, John Innes Centre, Norwich NR47UH, UK.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17556585" target="_blank"〉PubMed〈/a〉

    An X chromosome gene, WTX, is commonly inactivated in Wilms tumor (2007)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2007-01-06
    Description: Wilms tumor is a pediatric kidney cancer associated with inactivation of the WT1 tumor-suppressor gene in 5 to 10% of cases. Using a high-resolution screen for DNA copy-number alterations in Wilms tumor, we identified somatic deletions targeting a previously uncharacterized gene on the X chromosome. This gene, which we call WTX, is inactivated in approximately one-third of Wilms tumors (15 of 51 tumors). Tumors with mutations in WTX lack WT1 mutations, and both genes share a restricted temporal and spatial expression pattern in normal renal precursors. In contrast to biallelic inactivation of autosomal tumor-suppressor genes, WTX is inactivated by a monoallelic "single-hit" event targeting the single X chromosome in tumors from males and the active X chromosome in tumors from females.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rivera, Miguel N -- Kim, Woo Jae -- Wells, Julie -- Driscoll, David R -- Brannigan, Brian W -- Han, Moonjoo -- Kim, James C -- Feinberg, Andrew P -- Gerald, William L -- Vargas, Sara O -- Chin, Lynda -- Iafrate, A John -- Bell, Daphne W -- Haber, Daniel A -- P01-CA101942/CA/NCI NIH HHS/ -- R37 CA054358/CA/NCI NIH HHS/ -- R37 CA054358-17/CA/NCI NIH HHS/ -- R37-CA058596/CA/NCI NIH HHS/ -- T32-CA009216/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 2007 Feb 2;315(5812):642-5.

    GNAT-like strategy for polyketide chain initiation (2007)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2007-11-10
    Description: An unexpected biochemical strategy for chain initiation is described for the loading module of the polyketide synthase of curacin A, an anticancer lead derived from the marine cyanobacterium Lyngbya majuscula. A central GCN5-related N-acetyltransferase (GNAT) domain bears bifunctional decarboxylase/S-acetyltransferase activity, both unprecedented for the GNAT superfamily. A CurA loading tridomain, consisting of an adaptor domain, the GNAT domain, and an acyl carrier protein, was assessed biochemically, revealing that a domain showing homology to GNAT (GNAT(L)) catalyzes (i) decarboxylation of malonyl-coenzyme A (malonyl-CoA) to acetyl-CoA and (ii) direct S-acetyl transfer from acetyl-CoA to load an adjacent acyl carrier protein domain (ACP(L)). Moreover, the N-terminal adapter domain was shown to facilitate acetyl-group transfer. Crystal structures of GNAT(L) were solved at 1.95 angstroms (ligand-free form) and 2.75 angstroms (acyl-CoA complex), showing distinct substrate tunnels for acyl-CoA and holo-ACP(L) binding. Modeling and site-directed mutagenesis experiments demonstrated that histidine-389 and threonine-355, at the convergence of the CoA and ACP tunnels, participate in malonyl-CoA decarboxylation but not in acetyl-group transfer. Decarboxylation precedes acetyl-group transfer, leading to acetyl-ACP(L) as the key curacin A starter unit.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gu, Liangcai -- Geders, Todd W -- Wang, Bo -- Gerwick, William H -- Hakansson, Kristina -- Smith, Janet L -- Sherman, David H -- DK42303/DK/NIDDK NIH HHS/ -- GM076477/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2007 Nov 9;318(5852):970-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Life Sciences Institute, University of Michigan, Ann Arbor, MI 48109, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17991863" target="_blank"〉PubMed〈/a〉

    Structures of the CCR5 N terminus and of a tyrosine-sulfated antibody with HIV-1 gp120 and CD4 (2007)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2007-09-29
    Description: The CCR5 co-receptor binds to the HIV-1 gp120 envelope glycoprotein and facilitates HIV-1 entry into cells. Its N terminus is tyrosine-sulfated, as are many antibodies that react with the co-receptor binding site on gp120. We applied nuclear magnetic resonance and crystallographic techniques to analyze the structure of the CCR5 N terminus and that of the tyrosine-sulfated antibody 412d in complex with gp120 and CD4. The conformations of tyrosine-sulfated regions of CCR5 (alpha-helix) and 412d (extended loop) are surprisingly different. Nonetheless, a critical sulfotyrosine on CCR5 and on 412d induces similar structural rearrangements in gp120. These results now provide a framework for understanding HIV-1 interactions with the CCR5 N terminus during viral entry and define a conserved site on gp120, whose recognition of sulfotyrosine engenders posttranslational mimicry by the immune system.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2278242/" 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/PMC2278242/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Huang, Chih-Chin -- Lam, Son N -- Acharya, Priyamvada -- Tang, Min -- Xiang, Shi-Hua -- Hussan, Syed Shahzad-Ul -- Stanfield, Robyn L -- Robinson, James -- Sodroski, Joseph -- Wilson, Ian A -- Wyatt, Richard -- Bewley, Carole A -- Kwong, Peter D -- P30 AI060354/AI/NIAID NIH HHS/ -- U19 AI067854/AI/NIAID NIH HHS/ -- U19 AI067854-03/AI/NIAID NIH HHS/ -- Z99 AI999999/Intramural NIH HHS/ -- New York, N.Y. -- Science. 2007 Sep 28;317(5846):1930-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Vaccine Research Center, 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/17901336" target="_blank"〉PubMed〈/a〉

    The slit receptor EVA-1 coactivates a SAX-3/Robo mediated guidance signal in C. elegans (2007)

    Details
    Publication Date: 2007-09-29
    Description: The SAX-3/roundabout (Robo) receptor has SLT-1/Slit-dependent and -independent functions in guiding cell and axon migrations. We identified enhancer of ventral-axon guidance defects of unc-40 mutants (EVA-1) as a Caenorhabditis elegans transmembrane receptor for SLT-1. EVA-1 has two predicted galactose-binding ectodomains, acts cell-autonomously for SLT-1/Slit-dependent axon migration functions of SAX-3/Robo, binds to SLT-1 and SAX-3, colocalizes with SAX-3 on cells, and provides cell specificity to the activation of SAX-3 signaling by SLT-1. Double mutants of eva-1 or slt-1 with sax-3 mutations suggest that SAX-3 can (when slt-1 or eva-1 function is reduced) inhibit a parallel-acting guidance mechanism, which involves UNC-40/deleted in colorectal cancer.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Fujisawa, Kazuko -- Wrana, Jeffrey L -- Culotti, Joseph G -- NS41397/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 2007 Sep 28;317(5846):1934-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Samuel Lunenfeld Research Institute of Mount Sinai Hospital, 600 University Avenue, Toronto, Ontario M5G 1X5, Canada.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17901337" target="_blank"〉PubMed〈/a〉
