Chain F, Methyl-coenzyme M reductase I subunit gamma

Protein Classification

coenzyme-B sulfoethylthiotransferase subunit gamma( domain architecture ID 10491417)

coenzyme-B sulfoethylthiotransferase subunit gamma is a component of the methyl-coenzyme M reductase that catalyzes the reductive cleavage of methyl-coenzyme M using coenzyme B as reductant, which results in the production of methane and the mixed heterodisulfide of CoB and CoM

methyl-coenzyme M reductase, gamma subunit; Members of this protein family are the gamma subunit of methyl coenzyme M reductase, also called coenzyme-B sulfoethylthiotransferase (EC 2.8.4.1). This enzyme, with alpha, beta, and gamma subunits, catalyzes the last step in methanogenesis. Several methanogens have encode two such enzymes, designated I and II; this model does not separate the isozymes. [Energy metabolism, Methanogenesis]

methyl-coenzyme M reductase, gamma subunit; Members of this protein family are the gamma subunit of methyl coenzyme M reductase, also called coenzyme-B sulfoethylthiotransferase (EC 2.8.4.1). This enzyme, with alpha, beta, and gamma subunits, catalyzes the last step in methanogenesis. Several methanogens have encode two such enzymes, designated I and II; this model does not separate the isozymes. [Energy metabolism, Methanogenesis]
