Nitronate monooxygenase (EC 1.13.12.16, NMO) is an enzyme with systematic name nitronate:oxygen 2-oxidoreductase (nitrite-forming).[1][2][3][4] This enzyme catalyses the following chemical reaction

ethylnitronate + O2 [math]\displaystyle{ \rightleftharpoons }[/math] acetaldehyde + nitrite + other products

The enzymes from the fungus Neurospora crassa and the yeast Williopsis saturnus var. mrakii contain non-covalently bound FMN as the cofactor.
