CC   -!- FUNCTION: Nitronate monooxygenase that uses molecular oxygen to
CC       catalyze the oxidative denitrification of alkyl nitronates. Acts on
CC       propionate 3-nitronate (P3N), the presumed physiological substrate.
CC       Probably functions in the detoxification of P3N, a metabolic poison
CC       produced by plants and fungi as a defense mechanism.
CC       {ECO:0000250|UniProtKB:Q9HWH9}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=H2O + 3 O2 + 3 propionate 3-nitronate = 3 3-oxopropanoate + 3
CC         H(+) + H2O2 + 2 nitrate + nitrite; Xref=Rhea:RHEA:57332,
CC         ChEBI:CHEBI:15377, ChEBI:CHEBI:15378, ChEBI:CHEBI:15379,
CC         ChEBI:CHEBI:16240, ChEBI:CHEBI:16301, ChEBI:CHEBI:17632,
CC         ChEBI:CHEBI:33190, ChEBI:CHEBI:136067;
CC         Evidence={ECO:0000250|UniProtKB:D0V3Y4};
CC   -!- COFACTOR:
CC       Name=FMN; Xref=ChEBI:CHEBI:58210;
CC         Evidence={ECO:0000250|UniProtKB:Q9HWH9};
CC       Note=Binds 1 FMN per subunit. {ECO:0000250|UniProtKB:Q9HWH9};
CC   -!- MISCELLANEOUS: P3N is a potent irreversible inhibitor of the key enzyme
CC       succinate dehydrogenase in the Krebs cycle and electron transport
CC       chain. P3N has been shown to be a toxic metabolite to bacteria, plants,
CC       fungi, mammals or any organism that uses succinate dehydrogenase.
CC       {ECO:0000305}.
CC   -!- SIMILARITY: Belongs to the nitronate monooxygenase family. NMO class I
CC       subfamily. {ECO:0000305}.
