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 {ECO:0000255|HAMAP-Rule:MF_01173}.
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; Evidence={ECO:0000255|HAMAP-
CC Rule:MF_01173};
CC -!- COFACTOR:
CC Name=pyridoxal 5'-phosphate; Xref=ChEBI:CHEBI:597326;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_01173};
CC -!- PATHWAY: Amino-acid degradation; L-arginine degradation via AST
CC pathway; L-glutamate and succinate from L-arginine: step 3/5.
CC {ECO:0000255|HAMAP-Rule:MF_01173}.
CC -!- SIMILARITY: Belongs to the class-III pyridoxal-phosphate-dependent
CC aminotransferase family. AstC subfamily. {ECO:0000255|HAMAP-
CC Rule:MF_01173}.
