General annotation (Comments)

Function	Catalyzes the transamination of N(2)-succinylornithine and alpha-ketoglutarate into N(2)-succinylglutamate semialdehyde and glutamate. Can also act as an acetylornithine aminotransferase By similarity. HAMAP MF_01173
Catalytic activity	N(2)-succinyl-L-ornithine + 2-oxoglutarate = N-succinyl-L-glutamate 5-semialdehyde + L-glutamate. HAMAP MF_01173
Cofactor	Pyridoxal phosphate By similarity. HAMAP MF_01173
Pathway	Amino-acid degradation; L-arginine degradation via AST pathway; L-glutamate and succinate from L-arginine: step 3/5. HAMAP MF_01173
Sequence similarities	Belongs to the class-III pyridoxal-phosphate-dependent aminotransferase family. AstC subfamily.
