Glutamate 5-kinase

Gene

proB

Organism
Caldicellulosiruptor owensensis (strain ATCC 700167 / DSM 13100 / OL)
Status
Unreviewed-Annotation score: -Protein inferred from homologyi

Functioni

Catalyzes the transfer of a phosphate group to glutamate to form L-glutamate 5-phosphate.UniRule annotationSAAS annotation

Catalytic activityi

ATP + L-glutamate = ADP + L-glutamate 5-phosphate.UniRule annotationSAAS annotation

Pathwayi: L-proline biosynthesis

This protein is involved in step 1 of the subpathway that synthesizes L-glutamate 5-semialdehyde from L-glutamate.UniRule annotationSAAS 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.
