Thermus thermophilus (strain HB8 / ATCC 27634 / DSM 579)
Status
Reviewed-Annotation score: Annotation score: 3 out of 5-Protein inferred from homologyi

Functioni

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

Catalytic activityi

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

Similar proteinsi

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.
