KEGG   ENZYME: 1.18.1.4Help
Entry
EC 1.18.1.4                 Enzyme                                 

Name
rubredoxin---NAD(P)+ reductase;
rubredoxin-nicotinamide adenine dinucleotide (phosphate) reductase;
rubredoxin-nicotinamide adenine;
dinucleotide phosphate reductase;
NAD(P)+-rubredoxin oxidoreductase;
NAD(P)H-rubredoxin oxidoreductase
Class
Oxidoreductases;
Acting on iron-sulfur proteins as donors;
With NAD+ or NADP+ as acceptor
BRITE hierarchy
Sysname
rubredoxin:NAD(P)+ oxidoreductase
Reaction(IUBMB)
2 reduced rubredoxin + NAD(P)+ + H+ = 2 oxidized rubredoxin + NAD(P)H [RN:R02000 R02002]
Reaction(KEGG)
Substrate
reduced rubredoxin [CPD:C00340];
NAD+ [CPD:C00003];
NADP+ [CPD:C00006];
H+ [CPD:C00080]
Product
oxidized rubredoxin [CPD:C00435];
NADH [CPD:C00004];
NADPH [CPD:C00005]
Comment
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.
