Protein

Probable N-acetyl-gamma-glutamyl-phosphate reductase, chloroplastic

Gene

At2g19940

Organism
Arabidopsis thaliana (Mouse-ear cress)
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

Catalytic activityi

N-acetyl-L-glutamate 5-semialdehyde + NADP+ + phosphate = N-acetyl-5-glutamyl phosphate + NADPH.

Pathwayi: L-arginine biosynthesis

This protein is involved in step 3 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. Arginine biosynthesis bifunctional protein ArgJ, chloroplastic (AXX17_At2g34300), Probable amino-acid acetyltransferase NAGS2, chloroplastic (NAGS2), Probable amino-acid acetyltransferase NAGS1, chloroplastic (NAGS1), Arginine biosynthesis bifunctional protein ArgJ, chloroplastic (At2g37500)
  2. Acetylglutamate kinase, chloroplastic (NAGK)
  3. Probable N-acetyl-gamma-glutamyl-phosphate reductase, chloroplastic (At2g19940)
  4. Acetylornithine aminotransferase, chloroplastic/mitochondrial (WIN1)
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.
