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:0000256|HAMAP-
CC Rule:MF_01107};
CC -!- COFACTOR:
CC Name=pyridoxal 5'-phosphate; Xref=ChEBI:CHEBI:597326;
CC Evidence={ECO:0000256|HAMAP-Rule:MF_01107};
CC Note=Binds 1 pyridoxal phosphate per subunit. {ECO:0000256|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:0000256|HAMAP-
CC Rule:MF_01107}.
CC -!- SUBUNIT: Homodimer. {ECO:0000256|HAMAP-Rule:MF_01107}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000256|HAMAP-Rule:MF_01107}.
CC -!- MISCELLANEOUS: May also have succinyldiaminopimelate aminotransferase
CC activity, thus carrying out the corresponding step in lysine
CC biosynthesis. {ECO:0000256|HAMAP-Rule:MF_01107}.
CC -!- SIMILARITY: Belongs to the class-III pyridoxal-phosphate-dependent
CC aminotransferase family. ArgD subfamily. {ECO:0000256|HAMAP-
CC Rule:MF_01107}.
