    The genome of the blood fluke Schistosoma mansoni (2009)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2009-07-17
    Description: Schistosoma mansoni is responsible for the neglected tropical disease schistosomiasis that affects 210 million people in 76 countries. Here we present analysis of the 363 megabase nuclear genome of the blood fluke. It encodes at least 11,809 genes, with an unusual intron size distribution, and new families of micro-exon genes that undergo frequent alternative splicing. As the first sequenced flatworm, and a representative of the Lophotrochozoa, it offers insights into early events in the evolution of the animals, including the development of a body pattern with bilateral symmetry, and the development of tissues into organs. Our analysis has been informed by the need to find new drug targets. The deficits in lipid metabolism that make schistosomes dependent on the host are revealed, and the identification of membrane receptors, ion channels and more than 300 proteases provide new insights into the biology of the life cycle and new targets. Bioinformatics approaches have identified metabolic chokepoints, and a chemogenomic screen has pinpointed schistosome proteins for which existing drugs may be active. The information generated provides an invaluable resource for the research community to develop much needed new control tools for the treatment and eradication of this important and neglected disease.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2756445/" 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/PMC2756445/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Berriman, Matthew -- Haas, Brian J -- LoVerde, Philip T -- Wilson, R Alan -- Dillon, Gary P -- Cerqueira, Gustavo C -- Mashiyama, Susan T -- Al-Lazikani, Bissan -- Andrade, Luiza F -- Ashton, Peter D -- Aslett, Martin A -- Bartholomeu, Daniella C -- Blandin, Gaelle -- Caffrey, Conor R -- Coghlan, Avril -- Coulson, Richard -- Day, Tim A -- Delcher, Art -- DeMarco, Ricardo -- Djikeng, Appolinaire -- Eyre, Tina -- Gamble, John A -- Ghedin, Elodie -- Gu, Yong -- Hertz-Fowler, Christiane -- Hirai, Hirohisha -- Hirai, Yuriko -- Houston, Robin -- Ivens, Alasdair -- Johnston, David A -- Lacerda, Daniela -- Macedo, Camila D -- McVeigh, Paul -- Ning, Zemin -- Oliveira, Guilherme -- Overington, John P -- Parkhill, Julian -- Pertea, Mihaela -- Pierce, Raymond J -- Protasio, Anna V -- Quail, Michael A -- Rajandream, Marie-Adele -- Rogers, Jane -- Sajid, Mohammed -- Salzberg, Steven L -- Stanke, Mario -- Tivey, Adrian R -- White, Owen -- Williams, David L -- Wortman, Jennifer -- Wu, Wenjie -- Zamanian, Mostafa -- Zerlotini, Adhemar -- Fraser-Liggett, Claire M -- Barrell, Barclay G -- El-Sayed, Najib M -- 086151/Wellcome Trust/United Kingdom -- 5D43TW006580/TW/FIC NIH HHS/ -- 5D43TW007012-03/TW/FIC NIH HHS/ -- AI054711-01A2/AI/NIAID NIH HHS/ -- AI48828/AI/NIAID NIH HHS/ -- R01 GM083873/GM/NIGMS NIH HHS/ -- R01 GM083873-07/GM/NIGMS NIH HHS/ -- R01 GM083873-08/GM/NIGMS NIH HHS/ -- R01 LM006845/LM/NLM NIH HHS/ -- R01 LM006845-08/LM/NLM NIH HHS/ -- R01 LM006845-09/LM/NLM NIH HHS/ -- U01 AI048828/AI/NIAID NIH HHS/ -- U01 AI048828-01/AI/NIAID NIH HHS/ -- U01 AI048828-02/AI/NIAID NIH HHS/ -- WT085775/Z/08/Z/Wellcome Trust/United Kingdom -- England -- Nature. 2009 Jul 16;460(7253):352-8. doi: 10.1038/nature08160.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Wellcome Trust Sanger Institute, Cambridge CB10 1SD, UK. mb4@sanger.ac.uk〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19606141" target="_blank"〉PubMed〈/a〉

    Structural basis for outer membrane lipopolysaccharide insertion (2014)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2014-07-06
    Description: Lipopolysaccharide (LPS) is essential for most Gram-negative bacteria and has crucial roles in protection of the bacteria from harsh environments and toxic compounds, including antibiotics. Seven LPS transport proteins (that is, LptA-LptG) form a trans-envelope protein complex responsible for the transport of LPS from the inner membrane to the outer membrane, the mechanism for which is poorly understood. Here we report the first crystal structure of the unique integral membrane LPS translocon LptD-LptE complex. LptD forms a novel 26-stranded beta-barrel, which is to our knowledge the largest beta-barrel reported so far. LptE adopts a roll-like structure located inside the barrel of LptD to form an unprecedented two-protein 'barrel and plug' architecture. The structure, molecular dynamics simulations and functional assays suggest that the hydrophilic O-antigen and the core oligosaccharide of the LPS may pass through the barrel and the lipid A of the LPS may be inserted into the outer leaflet of the outer membrane through a lateral opening between strands beta1 and beta26 of LptD. These findings not only help us to understand important aspects of bacterial outer membrane biogenesis, but also have significant potential for the development of novel drugs against multi-drug resistant pathogenic bacteria.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Dong, Haohao -- Xiang, Quanju -- Gu, Yinghong -- Wang, Zhongshan -- Paterson, Neil G -- Stansfeld, Phillip J -- He, Chuan -- Zhang, Yizheng -- Wang, Wenjian -- Dong, Changjiang -- 083501/Z/07/Z/Wellcome Trust/United Kingdom -- England -- Nature. 2014 Jul 3;511(7507):52-6. doi: 10.1038/nature13464.

    Insights into hominid evolution from the gorilla genome sequence (2012)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2012-03-09
    Description: Gorillas are humans' closest living relatives after chimpanzees, and are of comparable importance for the study of human origins and evolution. Here we present the assembly and analysis of a genome sequence for the western lowland gorilla, and compare the whole genomes of all extant great ape genera. We propose a synthesis of genetic and fossil evidence consistent with placing the human-chimpanzee and human-chimpanzee-gorilla speciation events at approximately 6 and 10 million years ago. In 30% of the genome, gorilla is closer to human or chimpanzee than the latter are to each other; this is rarer around coding genes, indicating pervasive selection throughout great ape evolution, and has functional consequences in gene expression. A comparison of protein coding genes reveals approximately 500 genes showing accelerated evolution on each of the gorilla, human and chimpanzee lineages, and evidence for parallel acceleration, particularly of genes involved in hearing. We also compare the western and eastern gorilla species, estimating an average sequence divergence time 1.75 million years ago, but with evidence for more recent genetic exchange and a population bottleneck in the eastern species. The use of the genome sequence in these and future analyses will promote a deeper understanding of great ape biology and evolution.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3303130/" 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/PMC3303130/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Scally, Aylwyn -- Dutheil, Julien Y -- Hillier, LaDeana W -- Jordan, Gregory E -- Goodhead, Ian -- Herrero, Javier -- Hobolth, Asger -- Lappalainen, Tuuli -- Mailund, Thomas -- Marques-Bonet, Tomas -- McCarthy, Shane -- Montgomery, Stephen H -- Schwalie, Petra C -- Tang, Y Amy -- Ward, Michelle C -- Xue, Yali -- Yngvadottir, Bryndis -- Alkan, Can -- Andersen, Lars N -- Ayub, Qasim -- Ball, Edward V -- Beal, Kathryn -- Bradley, Brenda J -- Chen, Yuan -- Clee, Chris M -- Fitzgerald, Stephen -- Graves, Tina A -- Gu, Yong -- Heath, Paul -- Heger, Andreas -- Karakoc, Emre -- Kolb-Kokocinski, Anja -- Laird, Gavin K -- Lunter, Gerton -- Meader, Stephen -- Mort, Matthew -- Mullikin, James C -- Munch, Kasper -- O'Connor, Timothy D -- Phillips, Andrew D -- Prado-Martinez, Javier -- Rogers, Anthony S -- Sajjadian, Saba -- Schmidt, Dominic -- Shaw, Katy -- Simpson, Jared T -- Stenson, Peter D -- Turner, Daniel J -- Vigilant, Linda -- Vilella, Albert J -- Whitener, Weldon -- Zhu, Baoli -- Cooper, David N -- de Jong, Pieter -- Dermitzakis, Emmanouil T -- Eichler, Evan E -- Flicek, Paul -- Goldman, Nick -- Mundy, Nicholas I -- Ning, Zemin -- Odom, Duncan T -- Ponting, Chris P -- Quail, Michael A -- Ryder, Oliver A -- Searle, Stephen M -- Warren, Wesley C -- Wilson, Richard K -- Schierup, Mikkel H -- Rogers, Jane -- Tyler-Smith, Chris -- Durbin, Richard -- 062023/Wellcome Trust/United Kingdom -- 075491/Z/04/Wellcome Trust/United Kingdom -- 077009/Wellcome Trust/United Kingdom -- 077192/Wellcome Trust/United Kingdom -- 077198/Wellcome Trust/United Kingdom -- 089066/Wellcome Trust/United Kingdom -- 090532/Wellcome Trust/United Kingdom -- 095908/Wellcome Trust/United Kingdom -- 15603/Cancer Research UK/United Kingdom -- 202218/European Research Council/International -- A15603/Cancer Research UK/United Kingdom -- G0501331/Medical Research Council/United Kingdom -- G0701805/Medical Research Council/United Kingdom -- HG002385/HG/NHGRI NIH HHS/ -- U54 HG003079/HG/NHGRI NIH HHS/ -- WT062023/Wellcome Trust/United Kingdom -- WT077009/Wellcome Trust/United Kingdom -- WT077192/Wellcome Trust/United Kingdom -- WT077198/Wellcome Trust/United Kingdom -- WT089066/Wellcome Trust/United Kingdom -- Medical Research Council/United Kingdom -- Biotechnology and Biological Sciences Research Council/United Kingdom -- Howard Hughes Medical Institute/ -- Intramural NIH HHS/ -- England -- Nature. 2012 Mar 7;483(7388):169-75. doi: 10.1038/nature10842.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Wellcome Trust Sanger Institute, Wellcome Trust Genome Campus, Hinxton CB10 1SA, UK.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22398555" target="_blank"〉PubMed〈/a〉

    Structural basis of outer membrane protein insertion by the BAM complex (2016)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2016-02-24
    Description: All Gram-negative bacteria, mitochondria and chloroplasts have outer membrane proteins (OMPs) that perform many fundamental biological processes. The OMPs in Gram-negative bacteria are inserted and folded into the outer membrane by the beta-barrel assembly machinery (BAM). The mechanism involved is poorly understood, owing to the absence of a structure of the entire BAM complex. Here we report two crystal structures of the Escherichia coli BAM complex in two distinct states: an inward-open state and a lateral-open state. Our structures reveal that the five polypeptide transport-associated domains of BamA form a ring architecture with four associated lipoproteins, BamB-BamE, in the periplasm. Our structural, functional studies and molecular dynamics simulations indicate that these subunits rotate with respect to the integral membrane beta-barrel of BamA to induce movement of the beta-strands of the barrel and promote insertion of the nascent OMP.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gu, Yinghong -- Li, Huanyu -- Dong, Haohao -- Zeng, Yi -- Zhang, Zhengyu -- Paterson, Neil G -- Stansfeld, Phillip J -- Wang, Zhongshan -- Zhang, Yizheng -- Wang, Wenjian -- Dong, Changjiang -- G1100110/1/Medical Research Council/United Kingdom -- WT106121MA/Wellcome Trust/United Kingdom -- England -- Nature. 2016 Mar 3;531(7592):64-9. doi: 10.1038/nature17199.
