    Description: The 2,272,351-base pair genome of Neisseria meningitidis strain MC58 (serogroup B), a causative agent of meningitis and septicemia, contains 2158 predicted coding regions, 1158 (53.7%) of which were assigned a biological role. Three major islands of horizontal DNA transfer were identified; two of these contain genes encoding proteins involved in pathogenicity, and the third island contains coding sequences only for hypothetical proteins. Insights into the commensal and virulence behavior of N. meningitidis can be gleaned from the genome, in which sequences for structural proteins of the pilus are clustered and several coding regions unique to serogroup B capsular polysaccharide synthesis can be identified. Finally, N. meningitidis contains more genes that undergo phase variation than any pathogen studied to date, a mechanism that controls their expression and contributes to the evasion of the host immune system.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Tettelin, H -- Saunders, N J -- Heidelberg, J -- Jeffries, A C -- Nelson, K E -- Eisen, J A -- Ketchum, K A -- Hood, D W -- Peden, J F -- Dodson, R J -- Nelson, W C -- Gwinn, M L -- DeBoy, R -- Peterson, J D -- Hickey, E K -- Haft, D H -- Salzberg, S L -- White, O -- Fleischmann, R D -- Dougherty, B A -- Mason, T -- Ciecko, A -- Parksey, D S -- Blair, E -- Cittone, H -- Clark, E B -- Cotton, M D -- Utterback, T R -- Khouri, H -- Qin, H -- Vamathevan, J -- Gill, J -- Scarlato, V -- Masignani, V -- Pizza, M -- Grandi, G -- Sun, L -- Smith, H O -- Fraser, C M -- Moxon, E R -- Rappuoli, R -- Venter, J C -- New York, N.Y. -- Science. 2000 Mar 10;287(5459):1809-15.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉The Institute for Genomic Research (TIGR), 9712 Medical Center Drive, Rockville, MD 20850, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10710307" target="_blank"〉PubMed〈/a〉

    Description: The complete genome sequence of the radiation-resistant bacterium Deinococcus radiodurans R1 is composed of two chromosomes (2,648,638 and 412,348 base pairs), a megaplasmid (177,466 base pairs), and a small plasmid (45,704 base pairs), yielding a total genome of 3,284, 156 base pairs. Multiple components distributed on the chromosomes and megaplasmid that contribute to the ability of D. radiodurans to survive under conditions of starvation, oxidative stress, and high amounts of DNA damage were identified. Deinococcus radiodurans represents an organism in which all systems for DNA repair, DNA damage export, desiccation and starvation recovery, and genetic redundancy are present in one cell.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4147723/" 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/PMC4147723/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉White, O -- Eisen, J A -- Heidelberg, J F -- Hickey, E K -- Peterson, J D -- Dodson, R J -- Haft, D H -- Gwinn, M L -- Nelson, W C -- Richardson, D L -- Moffat, K S -- Qin, H -- Jiang, L -- Pamphile, W -- Crosby, M -- Shen, M -- Vamathevan, J J -- Lam, P -- McDonald, L -- Utterback, T -- Zalewski, C -- Makarova, K S -- Aravind, L -- Daly, M J -- Minton, K W -- Fleischmann, R D -- Ketchum, K A -- Nelson, K E -- Salzberg, S -- Smith, H O -- Venter, J C -- Fraser, C M -- R01 CA077712/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1999 Nov 19;286(5444):1571-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institute for Genomic Research, 9712 Medical Center Drive, Rockville, MD 20850, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10567266" target="_blank"〉PubMed〈/a〉

    Description: Dehalococcoides ethenogenes is the only bacterium known to reductively dechlorinate the groundwater pollutants, tetrachloroethene (PCE) and trichloroethene, to ethene. Its 1,469,720-base pair chromosome contains large dynamic duplicated regions and integrated elements. Genes encoding 17 putative reductive dehalogenases, nearly all of which were adjacent to genes for transcription regulators, and five hydrogenase complexes were identified. These findings, plus a limited repertoire of other metabolic modes, indicate that D. ethenogenes is highly evolved to utilize halogenated organic compounds and H2. Diversification of reductive dehalogenase functions appears to have been mediated by recent genetic exchange and amplification. Genome analysis provides insights into the organism's complex nutrient requirements and suggests that an ancestor was a nitrogen-fixing autotroph.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Seshadri, Rekha -- Adrian, Lorenz -- Fouts, Derrick E -- Eisen, Jonathan A -- Phillippy, Adam M -- Methe, Barbara A -- Ward, Naomi L -- Nelson, William C -- Deboy, Robert T -- Khouri, Hoda M -- Kolonay, James F -- Dodson, Robert J -- Daugherty, Sean C -- Brinkac, Lauren M -- Sullivan, Steven A -- Madupu, Ramana -- Nelson, Karen E -- Kang, Katherine H -- Impraim, Marjorie -- Tran, Kevin -- Robinson, Jeffrey M -- Forberger, Heather A -- Fraser, Claire M -- Zinder, Stephen H -- Heidelberg, John F -- New York, N.Y. -- Science. 2005 Jan 7;307(5706):105-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institute for Genomic Research, 9712 Medical Center Drive, Rockville, MD 20850, USA. rekha@tigr.org〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/15637277" target="_blank"〉PubMed〈/a〉

    Description: The complete genome sequence of Geobacter sulfurreducens, a delta-proteobacterium, reveals unsuspected capabilities, including evidence of aerobic metabolism, one-carbon and complex carbon metabolism, motility, and chemotactic behavior. These characteristics, coupled with the possession of many two-component sensors and many c-type cytochromes, reveal an ability to create alternative, redundant, electron transport networks and offer insights into the process of metal ion reduction in subsurface environments. As well as playing roles in the global cycling of metals and carbon, this organism clearly has the potential for use in bioremediation of radioactive metals and in the generation of electricity.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Methe, B A -- Nelson, K E -- Eisen, J A -- Paulsen, I T -- Nelson, W -- Heidelberg, J F -- Wu, D -- Wu, M -- Ward, N -- Beanan, M J -- Dodson, R J -- Madupu, R -- Brinkac, L M -- Daugherty, S C -- DeBoy, R T -- Durkin, A S -- Gwinn, M -- Kolonay, J F -- Sullivan, S A -- Haft, D H -- Selengut, J -- Davidsen, T M -- Zafar, N -- White, O -- Tran, B -- Romero, C -- Forberger, H A -- Weidman, J -- Khouri, H -- Feldblyum, T V -- Utterback, T R -- Van Aken, S E -- Lovley, D R -- Fraser, C M -- New York, N.Y. -- Science. 2003 Dec 12;302(5652):1967-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institute for Genomic Research, 9712 Medical Center Drive, Rockville, MD 20850, USA. bmethe@tigr.org〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/14671304" target="_blank"〉PubMed〈/a〉
