Protein

Ribosyldihydronicotinamide dehydrogenase [quinone]

Gene

NQO2

Organism
Homo sapiens (Human)
Status
Reviewed-Annotation score: Annotation score: 5 out of 5-Experimental evidence at protein leveli

Functioni

The enzyme apparently serves as a quinone reductase in connection with conjugation reactions of hydroquinones involved in detoxification pathways as well as in biosynthetic processes such as the vitamin K-dependent gamma-carboxylation of glutamate residues in prothrombin synthesis.1 Publication

Catalytic activityi

1-(beta-D-ribofuranosyl)-1,4-dihydronicotinamide + a quinone = 1-(beta-D-ribofuranosyl)nicotinamide + a quinol.1 Publication

Cofactori

Protein has several cofactor binding sites:
  • Zn2+Note: Binds 1 zinc ion per subunit.
  • FAD

Enzyme regulationi

Inhibited by melatonin, resveratrol and 5-hydroxytryptamine.1 Publication
