Reaction: 3-aci-nitropropanoate + O2 + H2O = 3-oxopropanoate + nitrite + H2O2
Other name(s): propionate-3-nitronate oxidase
Systematic name: 3-aci-nitropropanoate:oxygen oxidoreductase
Comments: A flavoprotein (FMN). The primary products of the enzymic reaction are probably the nitropropanoate free radical and superoxide. Also acts, more slowly, on 4-aci-nitrobutanoate.
