3-aci-nitropropanoate oxidase

In enzymology, a 3-aci-nitropropanoate oxidase () is an enzyme that catalyzes the chemical reaction
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.
