    Description: Only three biological pathways are known to produce oxygen: photosynthesis, chlorate respiration and the detoxification of reactive oxygen species. Here we present evidence for a fourth pathway, possibly of considerable geochemical and evolutionary importance. The pathway was discovered after metagenomic sequencing of an enrichment culture that couples anaerobic oxidation of methane with the reduction of nitrite to dinitrogen. The complete genome of the dominant bacterium, named 'Candidatus Methylomirabilis oxyfera', was assembled. This apparently anaerobic, denitrifying bacterium encoded, transcribed and expressed the well-established aerobic pathway for methane oxidation, whereas it lacked known genes for dinitrogen production. Subsequent isotopic labelling indicated that 'M. oxyfera' bypassed the denitrification intermediate nitrous oxide by the conversion of two nitric oxide molecules to dinitrogen and oxygen, which was used to oxidize methane. These results extend our understanding of hydrocarbon degradation under anoxic conditions and explain the biochemical mechanism of a poorly understood freshwater methane sink. Because nitrogen oxides were already present on early Earth, our finding opens up the possibility that oxygen was available to microbial metabolism before the evolution of oxygenic photosynthesis.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ettwig, Katharina F -- Butler, Margaret K -- Le Paslier, Denis -- Pelletier, Eric -- Mangenot, Sophie -- Kuypers, Marcel M M -- Schreiber, Frank -- Dutilh, Bas E -- Zedelius, Johannes -- de Beer, Dirk -- Gloerich, Jolein -- Wessels, Hans J C T -- van Alen, Theo -- Luesken, Francisca -- Wu, Ming L -- van de Pas-Schoonen, Katinka T -- Op den Camp, Huub J M -- Janssen-Megens, Eva M -- Francoijs, Kees-Jan -- Stunnenberg, Henk -- Weissenbach, Jean -- Jetten, Mike S M -- Strous, Marc -- England -- Nature. 2010 Mar 25;464(7288):543-8. doi: 10.1038/nature08883.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Radboud University Nijmegen, IWWR, Department of Microbiology, Heyendaalseweg 135, 6525 AJ, Nijmegen, The Netherlands. k.ettwig@science.ru.nl〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20336137" target="_blank"〉PubMed〈/a〉

    Description: Yeast artificial chromosomes (YACs) were obtained from a 550-kilobase region that contains three probes previously mapped as very close to the locus of the fragile X syndrome. These YACs spanned the fragile site in Xq27.3 as shown by fluorescent in situ hybridization. An internal 200-kilobase segment contained four chromosomal breakpoints generated by induction of fragile X expression. A single CpG island was identified in the cloned region between markers DXS463 and DXS465 that appears methylated in mentally retarded fragile X males, but not in nonexpressing male carriers of the mutation nor in normal males. This CpG island may indicate the presence of a gene involved in the clinical phenotype of the syndrome.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Heitz, D -- Rousseau, F -- Devys, D -- Saccone, S -- Abderrahim, H -- Le Paslier, D -- Cohen, D -- Vincent, A -- Toniolo, D -- Della Valle, G -- New York, N.Y. -- Science. 1991 Mar 8;251(4998):1236-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratoire de Genetique Moleculaire des Eucaryotes du CNRS, Institut de Chimie Biologique, Faculte de Medecine, Strasbourg, France.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2006411" target="_blank"〉PubMed〈/a〉

    Description: Our knowledge of species and functional composition of the human gut microbiome is rapidly increasing, but it is still based on very few cohorts and little is known about variation across the world. By combining 22 newly sequenced faecal metagenomes of individuals from four countries with previously published data sets, here we identify three robust clusters (referred to as enterotypes hereafter) that are not nation or continent specific. We also confirmed the enterotypes in two published, larger cohorts, indicating that intestinal microbiota variation is generally stratified, not continuous. This indicates further the existence of a limited number of well-balanced host-microbial symbiotic states that might respond differently to diet and drug intake. The enterotypes are mostly driven by species composition, but abundant molecular functions are not necessarily provided by abundant species, highlighting the importance of a functional analysis to understand microbial communities. Although individual host properties such as body mass index, age, or gender cannot explain the observed enterotypes, data-driven marker genes or functional modules can be identified for each of these host properties. For example, twelve genes significantly correlate with age and three functional modules with the body mass index, hinting at a diagnostic potential of microbial markers.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3728647/" 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/PMC3728647/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Arumugam, Manimozhiyan -- Raes, Jeroen -- Pelletier, Eric -- Le Paslier, Denis -- Yamada, Takuji -- Mende, Daniel R -- Fernandes, Gabriel R -- Tap, Julien -- Bruls, Thomas -- Batto, Jean-Michel -- Bertalan, Marcelo -- Borruel, Natalia -- Casellas, Francesc -- Fernandez, Leyden -- Gautier, Laurent -- Hansen, Torben -- Hattori, Masahira -- Hayashi, Tetsuya -- Kleerebezem, Michiel -- Kurokawa, Ken -- Leclerc, Marion -- Levenez, Florence -- Manichanh, Chaysavanh -- Nielsen, H Bjorn -- Nielsen, Trine -- Pons, Nicolas -- Poulain, Julie -- Qin, Junjie -- Sicheritz-Ponten, Thomas -- Tims, Sebastian -- Torrents, David -- Ugarte, Edgardo -- Zoetendal, Erwin G -- Wang, Jun -- Guarner, Francisco -- Pedersen, Oluf -- de Vos, Willem M -- Brunak, Soren -- Dore, Joel -- MetaHIT Consortium -- Antolin, Maria -- Artiguenave, Francois -- Blottiere, Herve M -- Almeida, Mathieu -- Brechot, Christian -- Cara, Carlos -- Chervaux, Christian -- Cultrone, Antonella -- Delorme, Christine -- Denariaz, Gerard -- Dervyn, Rozenn -- Foerstner, Konrad U -- Friss, Carsten -- van de Guchte, Maarten -- Guedon, Eric -- Haimet, Florence -- Huber, Wolfgang -- van Hylckama-Vlieg, Johan -- Jamet, Alexandre -- Juste, Catherine -- Kaci, Ghalia -- Knol, Jan -- Lakhdari, Omar -- Layec, Severine -- Le Roux, Karine -- Maguin, Emmanuelle -- Merieux, Alexandre -- Melo Minardi, Raquel -- M'rini, Christine -- Muller, Jean -- Oozeer, Raish -- Parkhill, Julian -- Renault, Pierre -- Rescigno, Maria -- Sanchez, Nicolas -- Sunagawa, Shinichi -- Torrejon, Antonio -- Turner, Keith -- Vandemeulebrouck, Gaetana -- Varela, Encarna -- Winogradsky, Yohanan -- Zeller, Georg -- Weissenbach, Jean -- Ehrlich, S Dusko -- Bork, Peer -- 076964/Wellcome Trust/United Kingdom -- 082372/Wellcome Trust/United Kingdom -- England -- Nature. 2011 May 12;473(7346):174-80. doi: 10.1038/nature09944.

    Description: To understand the impact of gut microbes on human health and well-being it is crucial to assess their genetic potential. Here we describe the Illumina-based metagenomic sequencing, assembly and characterization of 3.3 million non-redundant microbial genes, derived from 576.7 gigabases of sequence, from faecal samples of 124 European individuals. The gene set, approximately 150 times larger than the human gene complement, contains an overwhelming majority of the prevalent (more frequent) microbial genes of the cohort and probably includes a large proportion of the prevalent human intestinal microbial genes. The genes are largely shared among individuals of the cohort. Over 99% of the genes are bacterial, indicating that the entire cohort harbours between 1,000 and 1,150 prevalent bacterial species and each individual at least 160 such species, which are also largely shared. We define and describe the minimal gut metagenome and the minimal gut bacterial genome in terms of functions present in all individuals and most bacteria, respectively.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3779803/" 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/PMC3779803/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Qin, Junjie -- Li, Ruiqiang -- Raes, Jeroen -- Arumugam, Manimozhiyan -- Burgdorf, Kristoffer Solvsten -- Manichanh, Chaysavanh -- Nielsen, Trine -- Pons, Nicolas -- Levenez, Florence -- Yamada, Takuji -- Mende, Daniel R -- Li, Junhua -- Xu, Junming -- Li, Shaochuan -- Li, Dongfang -- Cao, Jianjun -- Wang, Bo -- Liang, Huiqing -- Zheng, Huisong -- Xie, Yinlong -- Tap, Julien -- Lepage, Patricia -- Bertalan, Marcelo -- Batto, Jean-Michel -- Hansen, Torben -- Le Paslier, Denis -- Linneberg, Allan -- Nielsen, H Bjorn -- Pelletier, Eric -- Renault, Pierre -- Sicheritz-Ponten, Thomas -- Turner, Keith -- Zhu, Hongmei -- Yu, Chang -- Li, Shengting -- Jian, Min -- Zhou, Yan -- Li, Yingrui -- Zhang, Xiuqing -- Li, Songgang -- Qin, Nan -- Yang, Huanming -- Wang, Jian -- Brunak, Soren -- Dore, Joel -- Guarner, Francisco -- Kristiansen, Karsten -- Pedersen, Oluf -- Parkhill, Julian -- Weissenbach, Jean -- MetaHIT Consortium -- Bork, Peer -- Ehrlich, S Dusko -- Wang, Jun -- 085775/Wellcome Trust/United Kingdom -- England -- Nature. 2010 Mar 4;464(7285):59-65. doi: 10.1038/nature08821.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉BGI-Shenzhen, Shenzhen 518083, China.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20203603" target="_blank"〉PubMed〈/a〉

    Description: Fragile sites are chemically induced nonstaining gaps in chromosomes. Different fragile sites vary in frequency in the population and in the chemistry of their induction. DNA sequences encompassing and including the rare, autosomal, folate-sensitive fragile site, FRA16A, were isolated by positional cloning. The molecular basis of FRA16A was found to be expansion of a normally polymorphic p(CCG)n repeat. This repeat was adjacent to a CpG island that was methylated in fragile site-expressing individuals. The FRA16A locus in individuals who do not express the fragile site is not a site of DNA methylation (imprinting), which suggests that the methylation associated with fragile sites may be a consequence and not a cause of their genesis.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Nancarrow, J K -- Kremer, E -- Holman, K -- Eyre, H -- Doggett, N A -- Le Paslier, D -- Callen, D F -- Sutherland, G R -- Richards, R I -- New York, N.Y. -- Science. 1994 Jun 24;264(5167):1938-41.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Cytogenetics and Molecular Genetics, Women's and Children's Hospital, North Adelaide, South Australia.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8009225" target="_blank"〉PubMed〈/a〉

    Description: Spinal muscular atrophies (SMAs) represent the second most common fatal autosomal recessive disorder after cystic fibrosis. Childhood spinal muscular atrophies are divided into severe (type I) and mild forms (types II and III). By a combination of genetic and physical mapping, a yeast artificial chromosome contig of the 5q13 region spanning the disease locus was constructed that showed the presence of low copy repeats in this region. Allele segregation was analyzed at the closest genetic loci detected by markers C212 and C272 in 201 SMA families. Inherited and de novo deletions were observed in nine unrelated SMA patients. Moreover, deletions were strongly suggested in at least 18 percent of SMA type I patients by the observation of marked heterozygosity deficiency for the loci studied. These results indicate that deletion events are statistically associated with the severe form of spinal muscular atrophy.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Melki, J -- Lefebvre, S -- Burglen, L -- Burlet, P -- Clermont, O -- Millasseau, P -- Reboullet, S -- Benichou, B -- Zeviani, M -- Le Paslier, D -- New York, N.Y. -- Science. 1994 Jun 3;264(5164):1474-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Unite de Recherches sur les Handicaps Genetiques de l'Enfant, INSERM U-393, Hopital des Enfants-Malades, Paris, France.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7910982" target="_blank"〉PubMed〈/a〉

    Description: The bacterial oxidation of nitrite to nitrate is a key process of the biogeochemical nitrogen cycle. Nitrite-oxidizing bacteria are considered a highly specialized functional group, which depends on the supply of nitrite from other microorganisms and whose distribution strictly correlates with nitrification in the environment and in wastewater treatment plants. On the basis of genomics, physiological experiments, and single-cell analyses, we show that Nitrospira moscoviensis, which represents a widely distributed lineage of nitrite-oxidizing bacteria, has the genetic inventory to utilize hydrogen (H2) as an alternative energy source for aerobic respiration and grows on H2 without nitrite. CO2 fixation occurred with H2 as the sole electron donor. Our results demonstrate a chemolithoautotrophic lifestyle of nitrite-oxidizing bacteria outside the nitrogen cycle, suggesting greater ecological flexibility than previously assumed.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Koch, Hanna -- Galushko, Alexander -- Albertsen, Mads -- Schintlmeister, Arno -- Gruber-Dorninger, Christiane -- Lucker, Sebastian -- Pelletier, Eric -- Le Paslier, Denis -- Spieck, Eva -- Richter, Andreas -- Nielsen, Per H -- Wagner, Michael -- Daims, Holger -- New York, N.Y. -- Science. 2014 Aug 29;345(6200):1052-4. doi: 10.1126/science.1256985.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Microbiology and Ecosystem Science, Division of Microbial Ecology, University of Vienna, 1090 Vienna, Austria. ; Center for Microbial Communities, Department of Biotechnology, Chemistry and Environmental Engineering, Aalborg University, 9000 Aalborg, Denmark. ; Department of Microbiology and Ecosystem Science, Division of Microbial Ecology, University of Vienna, 1090 Vienna, Austria.
