In enzymology, a nicotinate N-methyltransferase (EC 2.1.1.7) is an enzyme that catalyzes the chemical reaction
- S-adenosyl-L-methionine + nicotinate S-adenosyl-L-homocysteine + N-methylnicotinate
Thus, 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. The systematic name of this enzyme class is S-adenosyl-L-methionine:nicotinate N-methyltransferase. Other names in common use include furanocoumarin 8-methyltransferase, and furanocoumarin 8-O-methyltransferase. This enzyme participates in nicotinate and nicotinamide metabolism.
