Methyl-coenzyme M reductase (MCR) is the enzyme responsible for microbial formation of methane. It is a hexamer composed of 2 alpha (this family), 2 beta (Pfam:PF02241), and 2 gamma (Pfam:PF02240) subunits with two identical nickel porphinoid active sites [1]. The C-terminal domain is comprised of an all-alpha multi-helical bundle.	Domain
