General annotation (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. HAMAP MF_01106
Catalytic activity	N(2)-acetyl-L-ornithine + L-glutamate = L-ornithine + N-acetyl-L-glutamate. HAMAP MF_01106 Acetyl-CoA + L-glutamate = CoA + N-acetyl-L-glutamate. HAMAP MF_01106
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. HAMAP MF_01106 Amino-acid biosynthesis; L-arginine biosynthesis; N(2)-acetyl-L-ornithine from L-glutamate: step 1/4. HAMAP MF_01106
Subunit structure	Heterotetramer of two alpha and two beta chains By similarity. HAMAP MF_01106
Subcellular location	Cytoplasm Probable HAMAP MF_01106.
Miscellaneous	Some bacteria possess a monofunctional argJ, i.e., capable of catalyzing only the fifth step of the arginine biosynthetic pathway. HAMAP MF_01106
Sequence similarities	Belongs to the argJ family.
