MeTr subgroup of pterin binding enzymes. This family includes cobalamin-dependent methyltransferases such as methyltetrahydrofolate, corrinoid iron-sulfur protein methyltransferase (MeTr) and methionine synthase (MetH). Cobalamin-dependent methyltransferases catalyze the transfer of a methyl group via a methyl- cob(III)amide intermediate. These include MeTr, a functional heterodimer, and the folate binding domain of MetH.
