Accession ID Name Pfam Type
PF02745 Methyl-coenzyme M reductase alpha subunit, N-terminal domain domain

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 N-terminal domain has a ferredoxin-like fold.
