In enzymology a thiol S-methyltransferase (EC 2.1.1.9) is an enzyme that catalyzes the chemical reactionS-adenosyl-L-methionine + a thiol S-adenosyl-L-homocysteine + a thioetherThus the two substrates of this enzyme are S-adenosyl methionine and thiol whereas its two products are S-adenosylhomocysteine and thioether.This enzyme belongs to the family of transferases specifically those transferring one-carbon group methyltransferases.
