EC 1.6.3.4     
Accepted name: NADH oxidase (H2O-forming)
Reaction: 2 NADH + 2 H+ + O2 = 2 NAD+ + 2 H2O
Other name(s): H2O-forming NADH oxidase; Nox-2
Systematic name: NADH:oxygen oxidoreductase (H2O-forming)
Comments: A flavoprotein (FAD). The bacterium Streptococcus mutans contains two distinct NADH oxidases, a H2O-forming enzyme and a H2O2-forming enzyme (cf. EC 1.6.3.3, NADH oxidase (H2O2-forming)) [1].
