NAD/P/H_dehydrogenase_quinone_1 is an enzyme that in humans is encoded by the NQO1 gene. This protein-coding gene is a member of the NADH dehydrogenase (quinone) family and encodes a 2-electron reductase (enzyme). This FAD-binding protein forms homodimers and performs two-electron reduction of quinones to hydroquinones and of other redox dyes. It has a preference for short-chain acceptor quinones, such as ubiquinone, benzoquinone, juglone and duroquinone. This gene has an important paralog NQO2. This protein is located in the cytosol.
NQO1 enzyme expression can be induced by dioxin and inhibited by dicoumarol
The two-electron quinone reductase DT-diaphorase generates and maintains the antioxidant (reduced) form of coenzyme Q in membranes. 1997
The role of DT-diaphorase in the maintenance of the reduced antioxidant form of coenzyme Q in membrane systems. 1996
Addition of NADH and DT-diaphorase to either large unilamellar or multilamellar vesicles containing homologs of CoQ, including CoQ9 and CoQ10, resulted in the essentially complete reduction of the CoQ.
