== Function ==
[https://www.uniprot.org/uniprot/NMO_PSEAE NMO_PSEAE] Nitronate monooxygenase that uses molecular oxygen to catalyze the oxidative denitrification of alkyl nitronates. The toxin propionate 3-nitronate (P3N) is the best substrate (and the presumed physiological substrate), but this enzyme is also active on other primary and secondary nitronates such as propyl-1-nitronate, ethylnitronate, pentyl-1-nitronate, butyl-1-nitronate and propyl-2-nitronate (PubMed:25002579). Is likely involved in the degradation of P3N, that allows P.aeruginosa PAO1 to grow on 3-nitropropionate/P3N as the sole nitrogen source (PubMed:20382807). Also functions in the detoxification of P3N, a metabolic poison produced by plants and fungi as a defense mechanism (PubMed:25384477). Cannot oxidize nitroalkanes such as 3-nitropropionate, nitroethane, 1-nitropropane, 1-nitrobutane, 1-nitropentane, or 2-nitropropane (PubMed:25002579).<ref>PMID:20382807</ref> <ref>PMID:25002579</ref> <ref>PMID:25384477</ref>
