Functional Family NAD(P)H dehydrogenase [quinone] 1

Enzyme Information

1.6.5.2
NAD(P)H dehydrogenase (quinone).
based on mapping to UniProt P15559
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.
