In enzymology a trimethylsulfonium-tetrahydrofolate N-methyltransferase (EC 2.1.1.19) is an enzyme that catalyzes the chemical reactiontrimethylsulfonium + tetrahydrofolate dimethylsulfide + 5-methyltetrahydrofolateThus the two substrates of this enzyme are trimethylsulfonium and tetrahydrofolate whereas its two products are dimethyl sulfide and 5-methyltetrahydrofolate.This enzyme belongs to the family of transferases specifically those transferring one-carbon group methyltransferases.
