pfam02241: MCR_beta (This model is not part of the current CDD release)
Methyl-coenzyme M reductase beta subunit, C-terminal domain
Methyl-coenzyme M reductase (MCR) is the enzyme responsible for microbial formation of methane. It is a hexamer composed of 2 alpha (pfam02249), 2 beta (this family), and 2 gamma (pfam02240) subunits with two identical nickel porphinoid active sites. The C-terminal domain of MCR beta has an all-alpha fold with buried central helix.
