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.

Caution

Lacks conserved residue(s) required for the propagation of feature annotation.
The sequence shown here is derived from an EMBL/GenBank/DDBJ whole genome shotgun (WGS) entry which is preliminary data.

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.
