Enzyme Information

1.6.5.2

NAD(P)H dehydrogenase (quinone).

based on mapping to UniProt P0A754

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

-!- The enzyme catalyzes a two-electron reduction and has a preference for short-chain acceptor quinones, such as ubiquinone, benzoquinone, juglone and duroquinone. -!- The animal, but not the plant, form of the enzyme is inhibited by dicoumarol. -!- Formerly EC 1.6.99.2.
