Protein attributes

Sequence length	330 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is not processed.
Protein existence	Evidence at transcript level.

General annotation (Comments)

Function	Does not have alcohol dehydrogenase activity. Binds NADP and acts through a one-electron transfer process. Orthoquinones are the best substrates. May act in the detoxification of xenobiotics By similarity.
Catalytic activity	NADPH + 2 quinone = NADP(+) + 2 semiquinone.
Subunit structure	Homotetramer By similarity.
Subcellular location	Cytoplasm.
Sequence similarities	Belongs to the zinc-containing alcohol dehydrogenase family. Quinone oxidoreductase subfamily.
