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. Amino-acid acetyltransferase (argA)
  2. Acetylglutamate kinase (argB)
  3. N-acetyl-gamma-glutamyl-phosphate reductase (argC)
  4. Acetylornithine/succinyldiaminopimelate aminotransferase (argD)
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.

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
