acetaldehyde + FMN + nitrite + H2O + 2 H(+) => ethylnitronate + FMNH2 + O2
acetaldehyde + fmn + nitrite + h2o + 2 h(+) => ethylnitronate + fmnh2 + o2
acetaldehyde + FMN + nitrite + H2O + 2 H(+) => ethylnitronate + FMNH2 + O2
acetaldehyde + fmn + nitrite + h2o + 2 h(+) => ethylnitronate + fmnh2 + o2
