| 5-methyltetrahydrofolate-homocysteine s-methyltransferase | <enzyme> An enzyme that catalyses the formation of methionine by transfer of a methyl group from 5-methyltetrahydrofolate to homocysteine. It requires a cobamide coenzyme. The enzyme can act on mono- or triglutamate derivatives. Chemical name: 5-Methyltetrahydropteroyltri-L-glutamate:L-homocysteine S-methyltransferase Registry number: EC 2.1.1.13 (12 Dec 1998) |
