The 3 substrates of this enzyme are 3-aci-nitropropanoate, O₂, and H₂O, whereas its 3 products are 3-oxopropanoate, nitrite, and H₂O₂.

This enzyme belongs to the family of oxidoreductases, specifically those acting on other nitrogenous compounds as donors with oxygen as acceptor. The systematic name of this enzyme class is 3-aci-nitropropanoate:oxygen oxidoreductase. This enzyme is also called propionate-3-nitronate oxidase. It employs one cofactor, FMN.
