In enzymology a nicotinate dehydrogenase (EC 1.17.1.5) is an enzyme that catalyzes the chemical reactionnicotinate + H2O + NADP+ 6-hydroxynicotinate + NADPH + H+The 3 substrates of this enzyme are nicotinate H2O and NADP+ whereas its 3 products are 6-hydroxynicotinate NADPH and H+.This enzyme belongs to the family of oxidoreductases specifically those acting on CH or CH2 groups with NAD+ or NADP+ as acceptor.
