MTR [ENSP00000355536]
5-methyltetrahydrofolate-homocysteine methyltransferase; Catalyzes the transfer of a methyl group from methyl- cobalamin to homocysteine, yielding enzyme-bound cob(I)alamin and methionine. Subsequently, remethylates the cofactor using methyltetrahydrofolate (By similarity)
MMADHC [ENSP00000301920]
