Name | methyl-coenzyme M reductase |
Type | SYSTEM |
Description | Methyl-coenzyme M reductase is a nickel-containing, alpha2/beta2/gamma2 hexameric enzyme that catalyzes the final step in methanogenesis. This enzyme has several novel post-translational modifications; it is found in methanogenic archaea, many of which are hyperthermophiles. Many archaea have two versions of this enzyme. It appears that some Archaea are methanotrophic; homologous proteins act in the anaerobic oxidation of methane rather than in methanogenesis. |
