Abstract: The Archaeon Methanosarcina mazei and related species are of great ecological importance as they are the only organisms fermenting acetate, methylamines and methanol to methane, carbon dioxide and ammonia (in case of methylamines). Since acetate is the precursor of 60% of the methane produced on earth these organisms contribute significantly to the production of this greenhouse gas, e.g. in rice paddies. The 4,096,345 base pairs circular chromosome of M. mazei is more than twice as large as the genomes of the methanogenic Archaea currently completely sequenced (Bult et al., 1996; Smith et al., 1997). 3,371 open reading frames (ORFs) were identified. Based on currently available sequence data 376 of these ORFs are Methanosarcina-specific and 1,043 ORFs find their closest homologue in the ba... [Click above reference link for full abstract]
