Nicotinate dehydrogenase (cytochrome) (EC 1.17.2.1, nicotinic acid hydroxylase, nicotinate hydroxylase) is an enzyme with systematic name nicotinate:cytochrome 6-oxidoreductase (hydroxylating).^[1]^[2] This enzyme catalyses the following chemical reaction

nicotinate + a ferricytochrome + H₂O

\rightleftharpoons

6-hydroxynicotinate + a ferrocytochrome + 2 H⁺

This two-component enzyme from Pseudomonas belongs to the family of xanthine dehydrogenases.
