General annotation (Comments)

Function	Involved in both the arginine and lysine biosynthetic pathways By similarity. HAMAP MF_01107
Catalytic activity	N(2)-acetyl-L-ornithine + 2-oxoglutarate = N-acetyl-L-glutamate 5-semialdehyde + L-glutamate. HAMAP MF_01107 N-succinyl-L-2,6-diaminoheptanedioate + 2-oxoglutarate = N-succinyl-2-L-amino-6-oxoheptanedioate + L-glutamate. HAMAP MF_01107
Cofactor	Binds 1 pyridoxal phosphate per subunit By similarity. HAMAP MF_01107
Pathway	Amino-acid biosynthesis; L-arginine biosynthesis; N(2)-acetyl-L-ornithine from L-glutamate: step 4/4. HAMAP MF_01107 Amino-acid biosynthesis; L-lysine biosynthesis via DAP pathway; LL-2,6-diaminopimelate from (S)-tetrahydrodipicolinate (succinylase route): step 2/3. HAMAP MF_01107
Subunit structure	Homodimer By similarity. HAMAP MF_01107
Subcellular location	Cytoplasm Probable HAMAP MF_01107.
Miscellaneous	The reaction catalyzed by ACOAT is highly reversible. This enzyme may also transaminate ornithine By similarity. HAMAP MF_01107
Sequence similarities	Belongs to the class-III pyridoxal-phosphate-dependent aminotransferase family. ArgD subfamily.
