Catalytic activity RHEA:24292: acetyl-CoA + L-glutamate = CoA + H(+) + N-acetyl-L-glutamate
EC 2.3.1.1
Pathway Amino-acid biosynthesis; L-arginine biosynthesis; N(2)-acetyl-L-ornithine from L-glutamate: step 1/4.
case <OC:Enterobacterales>
Subunit Homohexamer.
end case
Subcellular location Cytoplasm.
case not <OC:Enterobacterales> and not <OC:Pseudomonadaceae> and not <OC:Vibrionaceae>
Miscellaneous In bacteria which possess the bifunctional enzyme ornithine acetyltransferase/N-acetylglutamate synthase (ArgJ), ArgA fulfills an anaplerotic role.
end case
Similarity Belongs to the acetyltransferase family. ArgA subfamily.
