IUBMB Enzyme Nomenclature

EC 1.18.1.4

Accepted name: rubredoxin—NAD(P)+ reductase

Reaction: 2 reduced rubredoxin + NAD(P)+ + H+ = 2 oxidized rubredoxin + NAD(P)H

Glossary: benzyl viologen = 1,1'-dibenzyl-4,4'-bipyridinium
2,6-dichloroindophenol = 4-(2,6-dichloro-4-hydroxyphenylimino)cyclohexa-2,5-dien-1-one
menadione = 2-methyl-1,4-naphthoquinone
rubredoxin

Other name(s): rubredoxin-nicotinamide adenine dinucleotide (phosphate) reductase; rubredoxin-nicotinamide adenine; dinucleotide phosphate reductase; NAD(P)+-rubredoxin oxidoreductase; NAD(P)H-rubredoxin oxidoreductase

Systematic name: rubredoxin:NAD(P)+ oxidoreductase

Comments: The enzyme from Pyrococcus furiosus requires FAD. It reduces a number of electron carriers, including benzyl viologen, menadione and 2,6-dichloroindophenol, but rubredoxin is the most efficient. Ferredoxin is not utilized.
