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.
