Enzyme Information
| 1.6.5.2 |
NAD(P)H dehydrogenase (quinone).
based on mapping to UniProt P05982
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.
