propionate-3-nitronate oxidase
Class
Oxidoreductases;
Acting on other nitrogenous compounds as donors;
With oxygen as acceptor
BRITE hierarchy
Sysname
3-aci-nitropropanoate:oxygen oxidoreductase
Reaction(IUBMB)
3-aci-nitropropanoate + O2 + H2O = 3-oxopropanoate + nitrite + H2O2 [RN:R01609]
Reaction(KEGG)
Substrate
3-aci-nitropropanoate [CPD:C03071];
O2 [CPD:C00007];
H2O [CPD:C00001]
Product
3-oxopropanoate [CPD:C00222];
nitrite [CPD:C00088];
H2O2 [CPD:C00027]
Comment
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.
History
