CC -!- FUNCTION: Catalyzes two activities which are involved in the cyclic
CC version of arginine biosynthesis: the synthesis of acetylglutamate from
CC glutamate and acetyl-CoA, and of ornithine by transacetylation between
CC acetylornithine and glutamate. {ECO:0000256|HAMAP-Rule:MF_03124}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=L-glutamate + N(2)-acetyl-L-ornithine = L-ornithine + N-
CC acetyl-L-glutamate; Xref=Rhea:RHEA:15349, ChEBI:CHEBI:29985,
CC ChEBI:CHEBI:44337, ChEBI:CHEBI:46911, ChEBI:CHEBI:57805; EC=2.3.1.35;
CC Evidence={ECO:0000256|ARBA:ARBA00000498, ECO:0000256|HAMAP-
CC Rule:MF_03124};
CC -!- CATALYTIC ACTIVITY:
CC Reaction=acetyl-CoA + L-glutamate = CoA + H(+) + N-acetyl-L-glutamate;
CC Xref=Rhea:RHEA:24292, ChEBI:CHEBI:15378, ChEBI:CHEBI:29985,
CC ChEBI:CHEBI:44337, ChEBI:CHEBI:57287, ChEBI:CHEBI:57288; EC=2.3.1.1;
CC Evidence={ECO:0000256|HAMAP-Rule:MF_03124};
CC -!- PATHWAY: Amino-acid biosynthesis; L-arginine biosynthesis; L-ornithine
CC and N-acetyl-L-glutamate from L-glutamate and N(2)-acetyl-L-ornithine
CC (cyclic): step 1/1. {ECO:0000256|HAMAP-Rule:MF_03124}.
CC -!- PATHWAY: Amino-acid biosynthesis; L-arginine biosynthesis; N(2)-acetyl-
CC L-ornithine from L-glutamate: step 1/4. {ECO:0000256|HAMAP-
CC Rule:MF_03124}.
CC -!- SUBUNIT: Heterodimer of an alpha and a beta chain. {ECO:0000256|HAMAP-
CC Rule:MF_03124}.
CC -!- SUBCELLULAR LOCATION: Plastid, chloroplast {ECO:0000256|HAMAP-
CC Rule:MF_03124}.
CC -!- SIMILARITY: Belongs to the ArgJ family. {ECO:0000256|ARBA:ARBA00006774,
CC ECO:0000256|HAMAP-Rule:MF_03124}.
CC -!- CAUTION: Lacks conserved residue(s) required for the propagation of
CC feature annotation. {ECO:0000256|HAMAP-Rule:MF_03124}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
