CC Reaction=L-aspartate + O2 = H2O2 + iminosuccinate;
CC Xref=Rhea:RHEA:25876, ChEBI:CHEBI:15379, ChEBI:CHEBI:16240,
CC ChEBI:CHEBI:29991, ChEBI:CHEBI:77875; EC=1.4.3.16;
CC Evidence={ECO:0000250|UniProtKB:P10902};
CC PhysiologicalDirection=left-to-right; Xref=Rhea:RHEA:25877;
CC Evidence={ECO:0000250|UniProtKB:P10902};
CC -!- COFACTOR:
CC Name=FAD; Xref=ChEBI:CHEBI:57692;
CC Evidence={ECO:0000250|UniProtKB:P10902};
CC Note=Binds 1 FAD per subunit. {ECO:0000250|UniProtKB:P10902};
CC -!- PATHWAY: Cofactor biosynthesis; NAD(+) biosynthesis; iminoaspartate
CC from L-aspartate (oxidase route): step 1/1.
CC {ECO:0000250|UniProtKB:P10902}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250|UniProtKB:P10902}.
CC -!- SIMILARITY: Belongs to the FAD-dependent oxidoreductase 2 family. NadB
CC subfamily. {ECO:0000305}.
