General annotation (Comments)

Catalytic activity	N(2)-acetyl-L-ornithine + 2-oxoglutarate = N-acetyl-L-glutamate 5-semialdehyde + L-glutamate. HAMAP MF_01107
Cofactor	Binds 1 pyridoxal phosphate per subunit By similarity.
Pathway	Amino-acid biosynthesis; L-arginine biosynthesis; N(2)-acetyl-L-ornithine from L-glutamate: step 4/4. HAMAP MF_01107
Subunit structure	Homodimer By similarity.
Subcellular location	Cytoplasm Probable.
Miscellaneous	May also have succinyldiaminopimelate aminotransferase activity, thus carrying out the corresponding step in lysine biosynthesis. HAMAP MF_01107
Sequence similarities	Belongs to the class-III pyridoxal-phosphate-dependent aminotransferase family. ArgD subfamily.
