MeSH Heading: Betaine-Homocysteine S-Methyltransferase
Tree Number(s): D08.811.913.555.500.175
Unique ID: D050940
RDF Unique Identifier: http://id.nlm.nih.gov/mesh/D050940
Scope Note: A ZINC metalloenzyme that catalyzes the transfer of a methyl group from BETAINE to HOMOCYSTEINE to produce dimethylglycine and METHIONINE, respectively. This enzyme is a member of a family of ZINC-dependent METHYLTRANSFERASES that use THIOLS or selenols as methyl acceptors.
Entry Term(s): Bet-HCys MTase; Betaine Homocysteine Methyltransferase; Betaine-Homocysteine Methyltransferase; Betaine-Homocysteine Methyltransferase 2; Betaine-Homocysteine Methyltransferase-2
