    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〉

    Asymmetry in the structure of the ABC transporter-binding protein complex BtuCD-BtuF (2007)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2007-08-04
    Description: BtuCD is an adenosine triphosphate-binding cassette (ABC) transporter that translocates vitamin B12 from the periplasmic binding protein BtuF into the cytoplasm of Escherichia coli. The 2.6 angstrom crystal structure of a complex BtuCD-F reveals substantial conformational changes as compared with the previously reported structures of BtuCD and BtuF. The lobes of BtuF are spread apart, and B12 is displaced from the binding pocket. The transmembrane BtuC subunits reveal two distinct conformations, and the translocation pathway is closed to both sides of the membrane. Electron paramagnetic resonance spectra of spin-labeled cysteine mutants reconstituted in proteoliposomes are consistent with the conformation of BtuCD-F that was observed in the crystal structure. A comparison with BtuCD and the homologous HI1470/71 protein suggests that the structure of BtuCD-F may reflect a posttranslocation intermediate.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hvorup, Rikki N -- Goetz, Birke A -- Niederer, Martina -- Hollenstein, Kaspar -- Perozo, Eduardo -- Locher, Kaspar P -- New York, N.Y. -- Science. 2007 Sep 7;317(5843):1387-90.

    Changes in regulation of a transcription factor lead to autogamy in cultivated tomatoes (2007)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2007-10-27
    Description: We report the cloning of Style2.1, the major quantitative trait locus responsible for a key floral attribute (style length) associated with the evolution of self-pollination in cultivated tomatoes. The gene encodes a putative transcription factor that regulates cell elongation in developing styles. The transition from cross-pollination to self-pollination was accompanied, not by a change in the STYLE2.1 protein, but rather by a mutation in the Style2.1 promoter that results in a down-regulation of Style2.1 expression during flower development.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chen, Kai-Yi -- Cong, Bin -- Wing, Rod -- Vrebalov, Julia -- Tanksley, Steven D -- New York, N.Y. -- Science. 2007 Oct 26;318(5850):643-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Plant Breeding and Genetics, Cornell University, Ithaca, NY 14853, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17962563" target="_blank"〉PubMed〈/a〉

    Structure of Nup58/45 suggests flexible nuclear pore diameter by intermolecular sliding (2007)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2007-03-24
    Description: The nucleoporins Nup58 and Nup45 are part of the central transport channel of the nuclear pore complex, which is thought to have a flexible diameter. In the crystal structure of an alpha-helical region of mammalian Nup58/45, we identified distinct tetramers, each consisting of two antiparallel hairpin dimers. The intradimeric interface is hydrophobic, whereas dimer-dimer association occurs through large hydrophilic residues. These residues are laterally displaced in various tetramer conformations, which suggests an intermolecular sliding by 11 angstroms. We propose that circumferential sliding plays a role in adjusting the diameter of the central transport channel.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Melcak, Ivo -- Hoelz, Andre -- Blobel, Gunter -- R01 GM111461/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2007 Mar 23;315(5819):1729-32.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory of Cell Biology, Howard Hughes Medical Institute, Rockefeller University, 1230 York Avenue, New York, NY 10021, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17379812" target="_blank"〉PubMed〈/a〉

    Structure of fungal fatty acid synthase and implications for iterative substrate shuttling (2007)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2007-04-14
    Description: We report crystal structures of the 2.6-megadalton alpha6beta6 heterododecameric fatty acid synthase from Thermomyces lanuginosus at 3.1 angstrom resolution. The alpha and beta polypeptide chains form the six catalytic domains required for fatty acid synthesis and numerous expansion segments responsible for extensive intersubunit connections. Detailed views of all active sites provide insights into substrate specificities and catalytic mechanisms and reveal their unique characteristics, which are due to the integration into the multienzyme. The mode of acyl carrier protein attachment in the reaction chamber, together with the spatial distribution of active sites, suggests that iterative substrate shuttling is achieved by a relatively restricted circular motion of the carrier domain in the multifunctional enzyme.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Jenni, Simon -- Leibundgut, Marc -- Boehringer, Daniel -- Frick, Christian -- Mikolasek, Bohdan -- Ban, Nenad -- New York, N.Y. -- Science. 2007 Apr 13;316(5822):254-61.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institute of Molecular Biology and Biophysics, ETH Zurich, 8092 Zurich, Switzerland.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17431175" target="_blank"〉PubMed〈/a〉

    Signals from chloroplasts converge to regulate nuclear gene expression (2007)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2007-03-31
    Description: Plastid-to-nucleus retrograde signaling coordinates nuclear gene expression with chloroplast function and is essential for the photoautotrophic life-style of plants. Three retrograde signals have been described, but little is known of their signaling pathways. We show here that GUN1, a chloroplast-localized pentatricopeptide-repeat protein, and ABI4, an Apetala 2 (AP2)-type transcription factor, are common to all three pathways. ABI4 binds the promoter of a retrograde-regulated gene through a conserved motif found in close proximity to a light-regulatory element. We propose a model in which multiple indicators of aberrant plastid function in Arabidopsis are integrated upstream of GUN1 within plastids, which leads to ABI4-mediated repression of nuclear-encoded genes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Koussevitzky, Shai -- Nott, Ajit -- Mockler, Todd C -- Hong, Fangxin -- Sachetto-Martins, Gilberto -- Surpin, Marci -- Lim, Jason -- Mittler, Ron -- Chory, Joanne -- DRG-1865-05/PHS HHS/ -- F32 GM 18172/GM/NIGMS NIH HHS/ -- F32 GM 69090/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2007 May 4;316(5825):715-9.

    Structure of the membrane protein FhaC: a member of the Omp85-TpsB transporter superfamily (2007)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2007-08-19
    Description: In Gram-negative bacteria and eukaryotic organelles, beta-barrel proteins of the outer membrane protein 85-two-partner secretion B (Omp85-TpsB) superfamily are essential components of protein transport machineries. The TpsB transporter FhaC mediates the secretion of Bordetella pertussis filamentous hemagglutinin (FHA). We report the 3.15 A crystal structure of FhaC. The transporter comprises a 16-stranded beta barrel that is occluded by an N-terminal alpha helix and an extracellular loop and a periplasmic module composed of two aligned polypeptide-transport-associated (POTRA) domains. Functional data reveal that FHA binds to the POTRA 1 domain via its N-terminal domain and likely translocates the adhesin-repeated motifs in an extended hairpin conformation, with folding occurring at the cell surface. General features of the mechanism obtained here are likely to apply throughout the superfamily.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Clantin, Bernard -- Delattre, Anne-Sophie -- Rucktooa, Prakash -- Saint, Nathalie -- Meli, Albano C -- Locht, Camille -- Jacob-Dubuisson, Francoise -- Villeret, Vincent -- New York, N.Y. -- Science. 2007 Aug 17;317(5840):957-61.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉UMR8161 CNRS, Institut de Biologie de Lille, Universite de Lille 1, Universite de Lille 2, 1 rue du Prof. Calmette, F-59021 Lille cedex, France.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17702945" target="_blank"〉PubMed〈/a〉

    A 3-hydroxypropionate/4-hydroxybutyrate autotrophic carbon dioxide assimilation pathway in Archaea (2007)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2007-12-15
    Description: The assimilation of carbon dioxide (CO2) into organic material is quantitatively the most important biosynthetic process. We discovered that an autotrophic member of the archaeal order Sulfolobales, Metallosphaera sedula, fixed CO2 with acetyl-coenzyme A (acetyl-CoA)/propionyl-CoA carboxylase as the key carboxylating enzyme. In this system, one acetyl-CoA and two bicarbonate molecules were reductively converted via 3-hydroxypropionate to succinyl-CoA. This intermediate was reduced to 4-hydroxybutyrate and converted into two acetyl-CoA molecules via 4-hydroxybutyryl-CoA dehydratase. The key genes of this pathway were found not only in Metallosphaera but also in Sulfolobus, Archaeoglobus, and Cenarchaeum species. Moreover, the Global Ocean Sampling database contains half as many 4-hydroxybutyryl-CoA dehydratase sequences as compared with those found for another key photosynthetic CO2-fixing enzyme, ribulose-1,5-bisphosphate carboxylase-oxygenase. This indicates the importance of this enzyme in global carbon cycling.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Berg, Ivan A -- Kockelkorn, Daniel -- Buckel, Wolfgang -- Fuchs, Georg -- New York, N.Y. -- Science. 2007 Dec 14;318(5857):1782-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Mikrobiologie, Fakultat Biologie, Universitat Freiburg, Schanzlestrasse 1, D-79104 Freiburg, Germany.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18079405" target="_blank"〉PubMed〈/a〉

    The slit receptor EVA-1 coactivates a SAX-3/Robo mediated guidance signal in C. elegans (2007)
    American Association for the Advancement of Science (AAAS)
    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〉

    RAP80 targets BRCA1 to specific ubiquitin structures at DNA damage sites (2007)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2007-05-26
    Description: Mutations affecting the BRCT domains of the breast cancer-associated tumor suppressor BRCA1 disrupt the recruitment of this protein to DNA double-strand breaks (DSBs). The molecular structures at DSBs recognized by BRCA1 are presently unknown. We report the interaction of the BRCA1 BRCT domain with RAP80, a ubiquitin-binding protein. RAP80 targets a complex containing the BRCA1-BARD1 (BRCA1-associated ring domain protein 1) E3 ligase and the deubiquitinating enzyme (DUB) BRCC36 to MDC1-gammaH2AX-dependent lysine(6)- and lysine(63)-linked ubiquitin polymers at DSBs. These events are required for cell cycle checkpoint and repair responses to ionizing radiation, implicating ubiquitin chain recognition and turnover in the BRCA1-mediated repair of DSBs.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2706583/" 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/PMC2706583/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sobhian, Bijan -- Shao, Genze -- Lilli, Dana R -- Culhane, Aedin C -- Moreau, Lisa A -- Xia, Bing -- Livingston, David M -- Greenberg, Roger A -- K08 CA106597/CA/NCI NIH HHS/ -- K08 CA106597-01A2/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 2007 May 25;316(5828):1198-202.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Dana-Farber Cancer Institute and Department of Genetics and Department of Medicine, Harvard Medical School, 44 Binney Street, Boston, MA 02115, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17525341" target="_blank"〉PubMed〈/a〉

    Functional divergence of former alleles in an ancient asexual invertebrate (2007)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2007-10-13
    Description: Theory suggests it should be difficult for asexual organisms to adapt to a changing environment because genetic diversity can only arise from mutations accumulating within direct antecedents and not through sexual exchange. In an asexual microinvertebrate, the bdelloid rotifer, we have observed a mechanism by which such organisms could acquire the diversity needed for adaptation. Gene copies most likely representing former alleles have diverged in function so that the proteins they encode play complementary roles in survival of dry conditions. One protein prevents desiccation-sensitive enzymes from aggregating during drying, whereas its counterpart does not have this activity, but is able to associate with phospholipid bilayers and is potentially involved in maintenance of membrane integrity. The functional divergence of former alleles observed here suggests that adoption of asexual reproduction could itself be an evolutionary mechanism for the generation of diversity.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Pouchkina-Stantcheva, Natalia N -- McGee, Brian M -- Boschetti, Chiara -- Tolleter, Dimitri -- Chakrabortee, Sohini -- Popova, Antoaneta V -- Meersman, Filip -- Macherel, David -- Hincha, Dirk K -- Tunnacliffe, Alan -- New York, N.Y. -- Science. 2007 Oct 12;318(5848):268-71.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institute of Biotechnology, University of Cambridge, Tennis Court Road, Cambridge CB2 1QT, UK.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17932297" target="_blank"〉PubMed〈/a〉

    Publication Date: 2007-04-14
    Description: We have used 19.9 million papers over 5 decades and 2.1 million patents to demonstrate that teams increasingly dominate solo authors in the production of knowledge. Research is increasingly done in teams across nearly all fields. Teams typically produce more frequently cited research than individuals do, and this advantage has been increasing over time. Teams now also produce the exceptionally high-impact research, even where that distinction was once the domain of solo authors. These results are detailed for sciences and engineering, social sciences, arts and humanities, and patents, suggesting that the process of knowledge creation has fundamentally changed.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wuchty, Stefan -- Jones, Benjamin F -- Uzzi, Brian -- New York, N.Y. -- Science. 2007 May 18;316(5827):1036-9.

    Genome transplantation in bacteria: changing one species to another (2007)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2007-06-30
    Description: As a step toward propagation of synthetic genomes, we completely replaced the genome of a bacterial cell with one from another species by transplanting a whole genome as naked DNA. Intact genomic DNA from Mycoplasma mycoides large colony (LC), virtually free of protein, was transplanted into Mycoplasma capricolum cells by polyethylene glycol-mediated transformation. Cells selected for tetracycline resistance, carried by the M. mycoides LC chromosome, contain the complete donor genome and are free of detectable recipient genomic sequences. These cells that result from genome transplantation are phenotypically identical to the M. mycoides LC donor strain as judged by several criteria.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lartigue, Carole -- Glass, John I -- Alperovich, Nina -- Pieper, Rembert -- Parmar, Prashanth P -- Hutchison, Clyde A 3rd -- Smith, Hamilton O -- Venter, J Craig -- New York, N.Y. -- Science. 2007 Aug 3;317(5838):632-8.

    Mechanism of two classes of cancer mutations in the phosphoinositide 3-kinase catalytic subunit (2007)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2007-07-14
    Description: Many human cancers involve up-regulation of the phosphoinositide 3-kinase PI3Kalpha, with oncogenic mutations identified in both the p110alpha catalytic and the p85alpha regulatory subunits. We used crystallographic and biochemical approaches to gain insight into activating mutations in two noncatalytic p110alpha domains-the adaptor-binding and the helical domains. A structure of the adaptor-binding domain of p110alpha in a complex with the p85alpha inter-Src homology 2 (inter-SH2) domain shows that oncogenic mutations in the adaptor-binding domain are not at the inter-SH2 interface but in a polar surface patch that is a plausible docking site for other domains in the holo p110/p85 complex. We also examined helical domain mutations and found that the Glu545 to Lys545 (E545K) oncogenic mutant disrupts an inhibitory charge-charge interaction with the p85 N-terminal SH2 domain. These studies extend our understanding of the architecture of PI3Ks and provide insight into how two classes of mutations that cause a gain in function can lead to cancer.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Miled, Nabil -- Yan, Ying -- Hon, Wai-Ching -- Perisic, Olga -- Zvelebil, Marketa -- Inbar, Yuval -- Schneidman-Duhovny, Dina -- Wolfson, Haim J -- Backer, Jonathan M -- Williams, Roger L -- GM55692/GM/NIGMS NIH HHS/ -- MC_U105184308/Medical Research Council/United Kingdom -- New York, N.Y. -- Science. 2007 Jul 13;317(5835):239-42.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Medical Research Council Laboratory of Molecular Biology, Hills Road, Cambridge CB2 2QH, UK.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17626883" target="_blank"〉PubMed〈/a〉

    Publication Date: 2007-03-31
    Description: Telomerase is a ribonucleoprotein enzyme complex that adds 5'-TTAGGG-3' repeats onto the ends of human chromosomes, providing a telomere maintenance mechanism for approximately 90% of human cancers. We have purified human telomerase approximately 10(8)-fold, with the final elution dependent on the enzyme's ability to catalyze nucleotide addition onto a DNA oligonucleotide of telomeric sequence, thereby providing specificity for catalytically active telomerase. Mass spectrometric sequencing of the protein components and molecular size determination indicated an enzyme composition of two molecules each of telomerase reverse transcriptase, telomerase RNA, and dyskerin.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Cohen, Scott B -- Graham, Mark E -- Lovrecz, George O -- Bache, Nicolai -- Robinson, Phillip J -- Reddel, Roger R -- New York, N.Y. -- Science. 2007 Mar 30;315(5820):1850-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Cancer Research Unit, Children's Medical Research Institute, 214 Hawkesbury Road, Westmead NSW 2145, Australia.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17395830" target="_blank"〉PubMed〈/a〉

    Childhood origins of adult resistance to science (2007)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2007-05-19
    Description: Resistance to certain scientific ideas derives in large part from assumptions and biases that can be demonstrated experimentally in young children and that may persist into adulthood. In particular, both adults and children resist acquiring scientific information that clashes with common-sense intuitions about the physical and psychological domains. Additionally, when learning information from other people, both adults and children are sensitive to the trustworthiness of the source of that information. Resistance to science, then, is particularly exaggerated in societies where nonscientific ideologies have the advantages of being both grounded in common sense and transmitted by trustworthy sources.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bloom, Paul -- Weisberg, Deena Skolnick -- New York, N.Y. -- Science. 2007 May 18;316(5827):996-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Psychology, Yale University, New Haven, CT 06520, USA. paul.bloom@yale.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17510356" target="_blank"〉PubMed〈/a〉

    PDZ domain binding selectivity is optimized across the mouse proteome (2007)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2007-07-21
    Description: PDZ domains have long been thought to cluster into discrete functional classes defined by their peptide-binding preferences. We used protein microarrays and quantitative fluorescence polarization to characterize the binding selectivity of 157 mouse PDZ domains with respect to 217 genome-encoded peptides. We then trained a multidomain selectivity model to predict PDZ domain-peptide interactions across the mouse proteome with an accuracy that exceeds many large-scale, experimental investigations of protein-protein interactions. Contrary to the current paradigm, PDZ domains do not fall into discrete classes; instead, they are evenly distributed throughout selectivity space, which suggests that they have been optimized across the proteome to minimize cross-reactivity. We predict that focusing on families of interaction domains, which facilitates the integration of experimentation and modeling, will play an increasingly important role in future investigations of protein function.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2674608/" 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/PMC2674608/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Stiffler, Michael A -- Chen, Jiunn R -- Grantcharova, Viara P -- Lei, Ying -- Fuchs, Daniel -- Allen, John E -- Zaslavskaia, Lioudmila A -- MacBeath, Gavin -- 1 RO1 GM072872-01/GM/NIGMS NIH HHS/ -- 5 T32 GM07598-25/GM/NIGMS NIH HHS/ -- R01 GM072872/GM/NIGMS NIH HHS/ -- R01 GM072872-04/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2007 Jul 20;317(5836):364-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Chemistry and Chemical Biology, Harvard University, 12 Oxford Street, Cambridge, MA 02138, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17641200" target="_blank"〉PubMed〈/a〉

    LeuT-desipramine structure reveals how antidepressants block neurotransmitter reuptake (2007)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2007-08-11
    Description: Tricyclic antidepressants exert their pharmacological effect-inhibiting the reuptake of serotonin, norepinephrine, and dopamine-by directly blocking neurotransmitter transporters (SERT, NET, and DAT, respectively) in the presynaptic membrane. The drug-binding site and the mechanism of this inhibition are poorly understood. We determined the crystal structure at 2.9 angstroms of the bacterial leucine transporter (LeuT), a homolog of SERT, NET, and DAT, in complex with leucine and the antidepressant desipramine. Desipramine binds at the inner end of the extracellular cavity of the transporter and is held in place by a hairpin loop and by a salt bridge. This binding site is separated from the leucine-binding site by the extracellular gate of the transporter. By directly locking the gate, desipramine prevents conformational changes and blocks substrate transport. Mutagenesis experiments on human SERT and DAT indicate that both the desipramine-binding site and its inhibition mechanism are probably conserved in the human neurotransmitter transporters.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3711652/" 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/PMC3711652/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Zhou, Zheng -- Zhen, Juan -- Karpowich, Nathan K -- Goetz, Regina M -- Law, Christopher J -- Reith, Maarten E A -- Wang, Da-Neng -- DA013261/DA/NIDA NIH HHS/ -- DA019676/DA/NIDA NIH HHS/ -- GM075026/GM/NIGMS NIH HHS/ -- GM075936/GM/NIGMS NIH HHS/ -- R01 DA013261/DA/NIDA NIH HHS/ -- R01 DA019676/DA/NIDA NIH HHS/ -- R01 DK053973/DK/NIDDK NIH HHS/ -- R21 DK060841/DK/NIDDK NIH HHS/ -- R21 GM075936/GM/NIGMS NIH HHS/ -- U54 GM075026/GM/NIGMS NIH HHS/ -- U54 GM095315/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2007 Sep 7;317(5843):1390-3.

    Stabilizing isopeptide bonds revealed in gram-positive bacterial pilus structure (2007)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2007-12-08
    Description: Many bacterial pathogens have long, slender pili through which they adhere to host cells. The crystal structure of the major pilin subunit from the Gram-positive human pathogen Streptococcus pyogenes at 2.2 angstroms resolution reveals an extended structure comprising two all-beta domains. The molecules associate in columns through the crystal, with each carboxyl terminus adjacent to a conserved lysine of the next molecule. This lysine forms the isopeptide bonds that link the subunits in native pili, validating the relevance of the crystal assembly. Each subunit contains two lysine-asparagine isopeptide bonds generated by an intramolecular reaction, and we find evidence for similar isopeptide bonds in other cell surface proteins of Gram-positive bacteria. The present structure explains the strength and stability of such Gram-positive pili and could facilitate vaccine development.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kang, Hae Joo -- Coulibaly, Fasseli -- Clow, Fiona -- Proft, Thomas -- Baker, Edward N -- New York, N.Y. -- Science. 2007 Dec 7;318(5856):1625-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Maurice Wilkins Centre for Molecular Biodiscovery, University of Auckland, Auckland 1010, New Zealand.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18063798" target="_blank"〉PubMed〈/a〉

    A membrane receptor for retinol binding protein mediates cellular uptake of vitamin A (2007)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2007-01-27
    Description: Vitamin A has diverse biological functions. It is transported in the blood as a complex with retinol binding protein (RBP), but the molecular mechanism by which vitamin A is absorbed by cells from the vitamin A-RBP complex is not clearly understood. We identified in bovine retinal pigment epithelium cells STRA6, a multitransmembrane domain protein, as a specific membrane receptor for RBP. STRA6 binds to RBP with high affinity and has robust vitamin A uptake activity from the vitamin A-RBP complex. It is widely expressed in embryonic development and in adult organ systems. The RBP receptor represents a major physiological mediator of cellular vitamin A uptake.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kawaguchi, Riki -- Yu, Jiamei -- Honda, Jane -- Hu, Jane -- Whitelegge, Julian -- Ping, Peipei -- Wiita, Patrick -- Bok, Dean -- Sun, Hui -- 5T32EY07026/EY/NEI NIH HHS/ -- New York, N.Y. -- Science. 2007 Feb 9;315(5813):820-5.

    A bacterial effector acts as a plant transcription factor and induces a cell size regulator (2007)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2007-10-27
    Description: Pathogenicity of many Gram-negative bacteria relies on the injection of effector proteins by type III secretion into eukaryotic cells, where they modulate host signaling pathways to the pathogen's benefit. One such effector protein injected by Xanthomonas into plants is AvrBs3, which localizes to the plant cell nucleus and causes hypertrophy of plant mesophyll cells. We show that AvrBs3 induces the expression of a master regulator of cell size, upa20, which encodes a transcription factor containing a basic helix-loop-helix domain. AvrBs3 binds to a conserved element in the upa20 promoter via its central repeat region and induces gene expression through its activation domain. Thus, AvrBs3 and likely other members of this family provoke developmental reprogramming of host cells by mimicking eukaryotic transcription factors.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kay, Sabine -- Hahn, Simone -- Marois, Eric -- Hause, Gerd -- Bonas, Ulla -- New York, N.Y. -- Science. 2007 Oct 26;318(5850):648-51.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institute of Biology, Department of Genetics, Martin-Luther-University Halle-Wittenberg, Weinbergweg 10, D-06120 Halle (Saale), Germany.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17962565" target="_blank"〉PubMed〈/a〉

    Structural basis for substrate delivery by acyl carrier protein in the yeast fatty acid synthase (2007)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2007-04-14
    Description: In the multifunctional fungal fatty acid synthase (FAS), the acyl carrier protein (ACP) domain shuttles reaction intermediates covalently attached to its prosthetic phosphopantetheine group between the different enzymatic centers of the reaction cycle. Here, we report the structure of the Saccharomyces cerevisiae FAS determined at 3.1 angstrom resolution with its ACP stalled at the active site of ketoacyl synthase. The ACP contacts the base of the reaction chamber through conserved, charge-complementary surfaces, which optimally position the ACP toward the catalytic cleft of ketoacyl synthase. The conformation of the prosthetic group suggests a switchblade mechanism for acyl chain delivery to the active site of the enzyme.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Leibundgut, Marc -- Jenni, Simon -- Frick, Christian -- Ban, Nenad -- New York, N.Y. -- Science. 2007 Apr 13;316(5822):288-90.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institute of Molecular Biology and Biophysics, ETH Zurich, 8092 Zurich, Switzerland.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17431182" target="_blank"〉PubMed〈/a〉

    Conformational switching in the fungal light sensor Vivid (2007)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2007-05-19
    Description: The Neurospora crassa photoreceptor Vivid tunes blue-light responses and modulates gating of the circadian clock. Crystal structures of dark-state and light-state Vivid reveal a light, oxygen, or voltage Per-Arnt-Sim domain with an unusual N-terminal cap region and a loop insertion that accommodates the flavin cofactor. Photoinduced formation of a cystein-flavin adduct drives flavin protonation to induce an N-terminal conformational change. A cysteine-to-serine substitution remote from the flavin adenine dinucleotide binding site decouples conformational switching from the flavin photocycle and prevents Vivid from sending signals in Neurospora. Key elements of this activation mechanism are conserved by other photosensors such as White Collar-1, ZEITLUPE, ENVOY, and flavin-binding, kelch repeat, F-BOX 1 (FKF1).〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3682417/" 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/PMC3682417/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Zoltowski, Brian D -- Schwerdtfeger, Carsten -- Widom, Joanne -- Loros, Jennifer J -- Bilwes, Alexandrine M -- Dunlap, Jay C -- Crane, Brian R -- GM079879-01/GM/NIGMS NIH HHS/ -- MH44651/MH/NIMH NIH HHS/ -- P01 GM068087/GM/NIGMS NIH HHS/ -- R01 GM034985/GM/NIGMS NIH HHS/ -- R01 GM034985-24/GM/NIGMS NIH HHS/ -- R37GM34985/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2007 May 18;316(5827):1054-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Chemistry and Chemical Biology, Cornell University, Ithaca, NY 14853, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17510367" target="_blank"〉PubMed〈/a〉

    DUBA: a deubiquitinase that regulates type I interferon production (2007)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2007-11-10
    Description: Production of type I interferon (IFN-I) is a critical host defense triggered by pattern-recognition receptors (PRRs) of the innate immune system. Deubiquitinating enzyme A (DUBA), an ovarian tumor domain-containing deubiquitinating enzyme, was discovered in a small interfering RNA-based screen as a regulator of IFN-I production. Reduction of DUBA augmented the PRR-induced IFN-I response, whereas ectopic expression of DUBA had the converse effect. DUBA bound tumor necrosis factor receptor-associated factor 3 (TRAF3), an adaptor protein essential for the IFN-I response. TRAF3 is an E3 ubiquitin ligase that preferentially assembled lysine-63-linked polyubiquitin chains. DUBA selectively cleaved the lysine-63-linked polyubiquitin chains on TRAF3, resulting in its dissociation from the downstream signaling complex containing TANK-binding kinase 1. A discrete ubiquitin interaction motif within DUBA was required for efficient deubiquitination of TRAF3 and optimal suppression of IFN-I. Our data identify DUBA as a negative regulator of innate immune responses.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kayagaki, Nobuhiko -- Phung, Qui -- Chan, Salina -- Chaudhari, Ruchir -- Quan, Casey -- O'Rourke, Karen M -- Eby, Michael -- Pietras, Eric -- Cheng, Genhong -- Bazan, J Fernando -- Zhang, Zemin -- Arnott, David -- Dixit, Vishva M -- New York, N.Y. -- Science. 2007 Dec 7;318(5856):1628-32.

    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〉
