Protein
Probable nitronate monooxygenase
Organism
Staphylococcus saprophyticus subsp. saprophyticus (strain ATCC 15305 / DSM 20229 / NCIMB 8711 / NCTC 7292 / S-41)
Function
Nitronate monooxygenase that uses molecular oxygen to catalyze the oxidative denitrification of alkyl nitronates. Acts on propionate 3-nitronate (P3N), the presumed physiological substrate. Probably functions in the detoxification of P3N, a metabolic poison produced by plants and fungi as a defense mechanism.
Similarity
Belongs to the nitronate monooxygenase family. NMO class I subfamily.
