Protein
NAD(P)H dehydrogenase [quinone] 1
Gene
NQO1
Organism
Cavia porcellus (Guinea pig)
Status
Reviewed - Annotation score: 3 out of 5 - Experimental evidence at transcript leveli

Functioni

The enzyme apparently serves as a quinone reductase in connection with conjugation reactions of hydroquinons involved in detoxification pathways as well as in biosynthetic processes such as the vitamin K-dependent gamma-carboxylation of glutamate residues in prothrombin synthesis By similarity.

Catalytic activityi

NAD(P)H + a quinone = NAD(P)+ + a hydroquinone.

Cofactori

FAD By similarity.
