Thus, 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. The systematic name of this enzyme class is trimethylsulfonium:tetrahydrofolate N-methyltransferase. This enzyme is also called trimethylsulfonium-tetrahydrofolate methyltransferase. This enzyme participates in one carbon pool by folate.
