Comments

FUNCTION: Catalyzes two activities which are involved in the cyclic version of arginine biosynthesis: the synthesis of acetylglutamate from glutamate and acetyl-CoA, and of ornithine by transacetylation between acetylornithine and glutamate (By similarity).
CATALYTIC ACTIVITY: N²-acetyl-L-ornithine + L-glutamate = L-ornithine + N-acetyl-L-glutamate.
CATALYTIC ACTIVITY: Acetyl-CoA + L-glutamate = CoA + N-acetyl-L-glutamate.
PATHWAY: Amino-acid biosynthesis; L-arginine biosynthesis; L-ornithine and N-acetyl-L-glutamate from L-glutamate and N(2)-acetyl-L-ornithine (cyclic): step 1/1 .
PATHWAY: Amino-acid biosynthesis; L-arginine biosynthesis; N(2)-acetyl-L-ornithine from L-glutamate: step 1/4 .
SUBUNIT: Heterotetramer of two alpha and two beta chains (By similarity).
SUBCELLULAR LOCATION: Cytoplasm (Probable).
MISCELLANEOUS: Some bacteria possess a monofunctional argJ, i.e., capable of catalyzing only the fifth step of the arginine biosynthetic pathway.
SIMILARITY: Belongs to the argJ family.
