Accession ID Name Pfam Type
PF02240 Methyl-coenzyme M reductase gamma subunit domain

Methyl-coenzyme M reductase (MCR) is the enzyme responsible for microbial formation of methane. It is a hexamer composed of 2 alpha (Pfam:PF02249), 2 beta (Pfam:PF02241), and 2 gamma (this family) subunits with two identical nickel porphinoid active sites [1].
