In enzymology a tRNA (cytosine-5-)-methyltransferase (EC 2.1.1.29) is an enzyme that catalyzes the chemical reactionS-adenosyl-L-methionine + tRNA S-adenosyl-L-homocysteine + tRNA containing 5-methylcytosineThus the two substrates of this enzyme are S-adenosyl methionine and tRNA whereas its two products are S-adenosylhomocysteine and tRNA containing 5-methylcytosine.This enzyme belongs to the family of transferases specifically those transferring one-carbon group methyltransferases.
