In enzymology a nicotinate N-methyltransferase (EC 2.1.1.7) is an enzyme that catalyzes the chemical reactionS-adenosyl-L-methionine + nicotinate S-adenosyl-L-homocysteine + N-methylnicotinateThus the two substrates of this enzyme are S-adenosyl methionine and nicotinate whereas its two products are S-adenosylhomocysteine and N-methylnicotinate.This enzyme belongs to the family of transferases specifically those transferring one-carbon group methyltransferases.
