Functioni

N-acetylglutamate synthase involved in arginine biosynthesis.2 Publications

Miscellaneous

Present with 112 molecules/cell in log phase SD medium.1 Publication

Catalytic activityi

Acetyl-CoA + L-glutamate = CoA + N-acetyl-L-glutamate.

Enzyme regulationi

Feedback inhibition by L-arginine.1 Publication

Pathwayi: L-arginine biosynthesis

This protein is involved in step 1 of the subpathway that synthesizes N(2)-acetyl-L-ornithine from L-glutamate.
Proteins known to be involved in the 4 steps of the subpathway in this organism are:
  1. Amino-acid acetyltransferase, mitochondrial (ARG2), Arginine biosynthesis bifunctional protein ArgJ, mitochondrial (ARG7)
  2. Protein ARG5,6, mitochondrial (ARG5,6)
  3. Protein ARG5,6, mitochondrial (ARG5,6)
  4. Acetylornithine aminotransferase, mitochondrial (ARG8)
This subpathway is part of the pathway L-arginine biosynthesis, which is itself part of Amino-acid biosynthesis.
View all proteins of this organism that are known to be involved in the subpathway that synthesizes N(2)-acetyl-L-ornithine from L-glutamate, the pathway L-arginine biosynthesis and in Amino-acid biosynthesis.
