Protein attributes

Sequence length	274 AA.
Sequence status	Complete.
Protein existence	Evidence at transcript level

General annotation (Comments)

Function	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 activity	NAD(P)H + a quinone = NAD(P)+ + a hydroquinone.
Cofactor	FAD By similarity.
Subunit structure	Homodimer By similarity.
Subcellular location	Cytoplasm By similarity.
Sequence similarities	Belongs to the NAD(P)H dehydrogenase (quinone) family.
