In enzymology, 6-hydroxynicotinate reductase (EC 1.3.7.1) is an enzyme that catalyzes the chemical reaction
+ reduced ferredoxin
+ oxidised ferredoxin
The two substrates of this enzyme are 6-hydroxynicotinic acid and reduced ferredoxin. Its products are 1,4,5,6-tetrahydro-6-oxonicotinic acid and oxidized ferredoxin. [1] [2]
This enzyme belongs to the family of oxidoreductases, specifically those acting on the CH-CH group of donor with an iron-sulfur protein as acceptor. The systematic name of this enzyme class is 6-oxo-1,4,5,6-tetrahydronicotinate:ferredoxin oxidoreductase. Other names in common use include 6-oxotetrahydronicotinate dehydrogenase, 6-hydroxynicotinic reductase, HNA reductase, and 1,4,5,6-tetrahydro-6-oxonicotinate:ferredoxin oxidoreductase.
