ID   1.17.2.1
DE   nicotinate dehydrogenase (cytochrome).
AN   nicotinate hydroxylase.
AN   nicotinic acid hydroxylase.
CA   2 Fe(III)-[cytochrome] + H2O + nicotinate = 6-hydroxynicotinate +
CA   2 Fe(II)-[cytochrome] + 2 H(+).
CC   -!- This two-component enzyme from Pseudomonas belongs to the family of
CC       xanthine dehydrogenases, but differs from most other members of this
CC       family.
CC   -!- While most members contain an FAD cofactor, the large subunit of this
CC       enzyme contains three c-type cytochromes, enabling it to interact
CC       with the electron transfer chain, probably by delivering the
CC       electrons to a cytochrome oxidase.
