In enzymology a thetin-homocysteine S-methyltransferase (EC 2.1.1.3) is an enzyme that catalyzes the chemical reactiondimethylsulfonioacetate + L-homocysteine S-methylthioglycolate + L-methionineThus the two substrates of this enzyme are dimethylsulfonioacetic acid and L-homocysteine whereas its two products are S-methylthioglycolic acid and L-methionine.This enzyme belongs to the family of transferases specifically those transferring one-carbon group methyltransferases.
