Biol. Chem. 276:25404-25410(2001). CC -!- FUNCTION: Catalyzes two activities which are involved in the CC cyclic version of arginine biosynthesis: the synthesis of CC acetylglutamate from glutamate and acetyl-CoA, and of ornithine by CC transacetylation between acetylornithine and glutamate. CC -!- CATALYTIC ACTIVITY: N(2)-acetyl-L-ornithine + L-glutamate = L- CC ornithine + N-acetyl-L-glutamate. CC -!- CATALYTIC ACTIVITY: Acetyl-CoA + L-glutamate = CoA + N-acetyl-L- CC glutamate. CC -!- ENZYME REGULATION: Feedback inhibition by L-arginine. CC -!- PATHWAY: Amino-acid biosynthesis; L-arginine biosynthesis; L- CC ornithine and N-acetyl-L-glutamate from L-glutamate and N(2)- CC acetyl-L-ornithine (cyclic): step 1/1. CC -!- PATHWAY: Amino-acid biosynthesis; L-arginine biosynthesis; N(2)- CC acetyl-L-ornithine from L-glutamate: step 1/4. CC -!- SUBUNIT: Heterotetramer of two alpha and two beta chains. CC -!- SUBCELLULAR LOCATION: Cytoplasm (Probable). CC -!- MISCELLANEOUS: Independently synthesized alpha and beta subunits CC do not reconstitute a functional protein. Self-catalyzed precursor CC cleavage is a necessary step to form an active enzyme, probably by CC directing appropriate folding and/or topological organization of CC the active site. CC -!- MISCELLANEOUS: Some bacteria possess a monofunctional argJ, i.e., CC capable of catalyzing only the fifth step of the arginine CC biosynthetic pathway. CC -!- SIMILARITY: Belongs to the argJ family.
