CC -!- FUNCTION: Catalyzes two activities which are involved in the cyclic
CC version of arginine biosynthesis: the synthesis of N-acetylglutamate
CC from glutamate and acetyl-CoA as the acetyl donor, and of ornithine by
CC transacetylation between N(2)-acetylornithine and glutamate.
CC {ECO:0000255|HAMAP-Rule:MF_01106}.
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:0000255|HAMAP-Rule:MF_01106};
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:0000255|HAMAP-Rule:MF_01106};
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:0000255|HAMAP-Rule:MF_01106}.
CC -!- PATHWAY: Amino-acid biosynthesis; L-arginine biosynthesis; N(2)-acetyl-
CC L-ornithine from L-glutamate: step 1/4. {ECO:0000255|HAMAP-
CC Rule:MF_01106}.
CC -!- SUBUNIT: Heterotetramer of two alpha and two beta chains.
CC {ECO:0000255|HAMAP-Rule:MF_01106}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_01106}.
CC -!- MISCELLANEOUS: Some bacteria possess a monofunctional ArgJ, i.e.
CC capable of catalyzing only the fifth step of the arginine biosynthetic
CC pathway.
CC -!- SIMILARITY: Belongs to the ArgJ family. {ECO:0000255|HAMAP-
CC Rule:MF_01106}.
