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. Is likely involved in the degradation of P3N, that allows Pseudomonas sp. JS189 to grow on 3-nitropropionate/P3N as the sole source of nitrogen, carbon, and energy (PubMed:20382807). Also probably functions in the detoxification of P3N, a metabolic poison produced by plants and fungi as a defense mechanism (By similarity). Is not active against 3-nitropropionate, nor with neutral or nitronate forms of 1-nitropropane, 2-nitropropane, nitroethane, nitromethane, 1-nitropentane, and 2-nitroethanol (PubMed:20382807).
