| Comment | This model describes N5-methyltetrahydromethanopterin:
coenzyme M methyltransferase subunit A in methanogenic archaea. This methyltranferase is a membrane-associated enzyme complex that uses methyl-transfer reaction to drive sodium-ion pump. Archaea have evolved energy-yielding pathways marked by one-carbon biochemistry featuring novel cofactors and enzymes. This transferase (encoded by subunit A) is involved in the transfer of 'methyl' group from N5-methyltetrahydromethanopterin to coenzyme M. In an accompanying reaction, methane is produced by two-electron reduction of methyl-coenzyme M by another enzyme, methyl-coenzyme M reductase. |
