CommentMembers of this protein family are the beta subunit of methyl coenzyme M reductase, also called coenzyme-B sulfoethylthiotransferase (EC 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.
