Function

function

Catalyzes two activities which are involved in the cyclic version of arginine biosynthesis: the synthesis of N-acetylglutamate from glutamate and acetyl-CoA as the acetyl donor, and of ornithine by transacetylation between N2-acetylornithine and glutamate.

Miscellaneous

Some bacteria possess a monofunctional ArgJ, i.e., capable of catalyzing only the fifth step of the arginine biosynthetic pathway.

Catalytic activity

Pathway

Amino-acid biosynthesis; L-arginine biosynthesis; L-ornithine and N-acetyl-L-glutamate from L-glutamate and N2-acetyl-L-ornithine (cyclic): step 1/1.
Amino-acid biosynthesis; L-arginine biosynthesis; N2-acetyl-L-ornithine from L-glutamate: step 1/4.
