| Product Name | NADH oxidase (H2O2-forming) |
| Example Structure | ![]() |
| Synonyms | AF0395, H202-forming NADH oxidase, H2O2-forming NADH oxidase, H2O2-forming reduced nicotinamide adenine dinucleotide oxidase, MJ0649, MJNox, NADH:O2 oxidoreductase, NOX, Nox-1, NOX1, NoxA-1, NoxA2, NoxB-1, PH0311, PhNOX |
| EC Number | 1.6.3.3 |
| CAS Registry Number | |
| Comments | A flavoprotein (FAD). The bacterium Streptococcus mutans contains two distinct NADH oxidases, a H2O2-forming enzyme and a H2O-forming enzyme (cf. EC 1.6.3.4, NADH oxidase (H2O-forming)) [1]. The enzymes from the anaerobic archaea Methanocaldococcus jannaschii [6] and Pyrococcus furiosus [3] also produce low amounts of H2O. Unlike EC 1.6.3.1 (NAD(P)H oxidase) it has no activity towards NADPH. |
| Cofactor | FAD |
