CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=2-oxoglutarate + N(2)-acetyl-L-ornithine = L-glutamate + N-
CC         acetyl-L-glutamate 5-semialdehyde; Xref=Rhea:RHEA:18049,
CC         ChEBI:CHEBI:16810, ChEBI:CHEBI:29123, ChEBI:CHEBI:29985,
CC         ChEBI:CHEBI:57805; EC=2.6.1.11; Evidence={ECO:0000255|HAMAP-
CC         Rule:MF_01107};
CC   -!- COFACTOR:
CC       Name=pyridoxal 5'-phosphate; Xref=ChEBI:CHEBI:597326;
CC         Evidence={ECO:0000255|HAMAP-Rule:MF_01107};
CC       Note=Binds 1 pyridoxal phosphate per subunit. {ECO:0000255|HAMAP-
CC       Rule:MF_01107};
CC   -!- PATHWAY: Amino-acid biosynthesis; L-arginine biosynthesis; N(2)-acetyl-
CC       L-ornithine from L-glutamate: step 4/4. {ECO:0000255|HAMAP-
CC       Rule:MF_01107}.
CC   -!- SUBUNIT: Homodimer. {ECO:0000255|HAMAP-Rule:MF_01107}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_01107}.
CC   -!- MISCELLANEOUS: May also have succinyldiaminopimelate aminotransferase
CC       activity, thus carrying out the corresponding step in lysine
CC       biosynthesis. {ECO:0000255|HAMAP-Rule:MF_01107}.
CC   -!- SIMILARITY: Belongs to the class-III pyridoxal-phosphate-dependent
CC       aminotransferase family. ArgD subfamily. {ECO:0000255|HAMAP-
CC       Rule:MF_01107}.
