CC   -!- FUNCTION: Catalyzes the transamination of N(2)-succinylornithine and
CC       alpha-ketoglutarate into N(2)-succinylglutamate semialdehyde and
CC       glutamate. Can also act as an acetylornithine aminotransferase.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=2-oxoglutarate + N(2)-succinyl-L-ornithine = L-glutamate + N-
CC         succinyl-L-glutamate 5-semialdehyde; Xref=Rhea:RHEA:16953,
CC         ChEBI:CHEBI:16810, ChEBI:CHEBI:29985, ChEBI:CHEBI:58514,
CC         ChEBI:CHEBI:58520; EC=2.6.1.81;
CC   -!- COFACTOR:
CC       Name=pyridoxal 5'-phosphate; Xref=ChEBI:CHEBI:597326;
CC   -!- PATHWAY: Amino-acid degradation; L-arginine degradation via AST
CC       pathway; L-glutamate and succinate from L-arginine: step 3/5.
CC   -!- SIMILARITY: Belongs to the class-III pyridoxal-phosphate-dependent
CC       aminotransferase family. AstC subfamily.
