Protein

Guanosine-5'-triphosphate,3'-diphosphate pyrophosphatase

Gene

gppA

Organism
Shigella flexneri
Status
Reviewed-Annotation score: -Protein inferred from homologyi

Functioni

Catalyzes the conversion of pppGpp to ppGpp. Guanosine pentaphosphate (pppGpp) is a cytoplasmic signaling molecule which together with ppGpp controls the "stringent response", an adaptive process that allows bacteria to respond to amino acid starvation, resulting in the coordinated regulation of numerous cellular activities.UniRule annotation

Catalytic activityi

Guanosine 5'-triphosphate,3'-diphosphate + H2O = guanosine 3',5'-bis(diphosphate) + phosphate.UniRule annotation

Pathwayi: ppGpp biosynthesis

This protein is involved in step 2 of the subpathway that synthesizes ppGpp from GTP.UniRule annotation
Proteins known to be involved in the 2 steps of the subpathway in this organism are:
  1. GTP pyrophosphokinase (relA)
  2. Guanosine-5'-triphosphate,3'-diphosphate pyrophosphatase (gppA), Guanosine-5'-triphosphate,3'-diphosphate pyrophosphatase (gppA), Guanosine-5'-triphosphate,3'-diphosphate pyrophosphatase (gppA), Guanosine-5'-triphosphate,3'-diphosphate pyrophosphatase (gppA)
This subpathway is part of the pathway ppGpp biosynthesis, which is itself part of Purine metabolism.
View all proteins of this organism that are known to be involved in the subpathway that synthesizes ppGpp from GTP, the pathway ppGpp biosynthesis and in Purine metabolism.
