Protein

Gamma-glutamyl phosphate reductase

Gene

proA

Organism
Pseudomonas fluorescens (strain Pf0-1)
Status
Reviewed-Annotation score: -Protein inferred from homologyi

Functioni

Catalyzes the NADPH-dependent reduction of L-glutamate 5-phosphate into L-glutamate 5-semialdehyde and phosphate. The product spontaneously undergoes cyclization to form 1-pyrroline-5-carboxylate.UniRule annotation

Catalytic activityi

L-glutamate 5-semialdehyde + phosphate + NADP+ = L-glutamyl 5-phosphate + NADPH.UniRule annotation

Pathwayi: L-proline biosynthesis

This protein is involved in step 2 of the subpathway that synthesizes L-glutamate 5-semialdehyde from L-glutamate.UniRule annotation
Proteins known to be involved in the 2 steps of the subpathway in this organism are:
  1. Glutamate 5-kinase (proB)
  2. Gamma-glutamyl phosphate reductase (proA)
This subpathway is part of the pathway L-proline 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 L-glutamate 5-semialdehyde from L-glutamate, the pathway L-proline biosynthesis and in Amino-acid biosynthesis.
