Enzyme Information
| 1.10.5.1 |
Ribosyldihydronicotinamide dehydrogenase (quinone).
based on mapping to UniProt P16083
1-(beta-D-ribofuranosyl)-1,4-dihydronicotinamide + a quinone = 1-(beta-D- ribofuranosyl)nicotinamide + a quinol.
-!- Unlike EC 1.6.5.2, this quinone reductase cannot use NADH or NADPH; instead it uses N-ribosyl- and N-alkyldihydronicotinamides. -!- Polycyclic aromatic hydrocarbons, such as benz[a]anthracene, and the estrogens 17-beta-estradiol and diethylstilbestrol are potent inhibitors, but dicoumarol is only a very weak inhibitor. -!- This enzyme can catalyze both 2-electron and 4-electron reductions, but one-electron acceptors, such as potassium ferricyanide, cannot be reduced. -!- Formerly EC 1.10.99.2.
