The Methanosphaera stadtmanae DSM 3091 genome is 1.77 Million bp long and contains approximately 1588 predicted genes.

The sequence was released 01/05/2006 by the University of Goettingen, and was described in J Bacteriol 188:642-58 (2006) Fricke WF, Seedorf H, Henne A, Kruer M, Liesegang H, et al.  "The genome sequence of Methanosphaera stadtmanae reveals why this human intestinal archaeon is restricted to methanol and H2 for methane formation and ATP synthesis. "
Abstract: Methanosphaera stadtmanae has the most restricted energy metabolism of all methanogenic archaea. This human intestinal inhabitant can generate methane only by reduction of methanol with H2 and is dependent on acetate as a carbon source. We report here the genome sequence of M. stadtmanae, which was found to be composed of 1,767,403 bp with an average G+C content of 28% and to harbor only 1,534 protein-encoding sequences (CDS). The genome lacks 37 CDS present in the genomes of all other methanogens. Among these are the CDS for synthesis of molybdopterin and for synthesis of the carbon monoxide dehydrogenase/acetyl-coenzyme A synthase complex, which explains why M. stadtmanae cannot reduce CO2 to methane or oxidize methanol to CO2 and why this archaeon is dependent on acetate for biosynthesi...

The Archaeal Genome Browsers at UCSC were developed by members of the Lowe Lab (Kevin Schneider, Katherine Pollard, Andy Pohl, Todd Lowe) and Robert Baertsch, with significant support from the UCSC Human Genome Browser group. The Archaeal Browsers are run by a slightly modified version of the UCSC Human Genome Browser system. All queries, bug reports, content corrections, suggested improvements, and new track data submissions should be sent to Todd Lowe (lowe @soe.ucsc.edu).
