Alternative ProductsEvent=Alternative splicing; Named isoforms=3; Name=1; IsoId=P15559-1; Sequence=Displayed; Name=2; IsoId=P15559-2; Sequence=VSP_042716; Note=No experimental confirmation available.; Name=3; IsoId=P15559-3; Sequence=VSP_044446; Note=No experimental confirmation available.;
Catalytic ActivityNAD(P)H + a quinone = NAD(P)(+) + a hydroquinone.
CofactorName=FAD; Xref=ChEBI
Enzyme RegulationInhibited by dicoumarol.
FunctionThe 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.
InductionBy dioxin.
