IUBMB Enzyme Nomenclature


Accepted name: 3-aci-nitropropanoate oxidase

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.
