CommentThis subfamily is closely related to, yet is distinct from, uroporphyrinogen decarboxylase (EC 4.1.1.37). It includes two isozymes from Methanosarcina barkeri of methylcobalamin--coenzyme M methyltransferase. It also includes a chloromethane utilization protein, CmuA, which transfers the methyl group of chloromethane to a corrinoid protein.
