Protein

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

Gene

gppA

Organism
Escherichia coli O157:H7
Status
Reviewed-Annotation score: Annotation score: 2 out of 5-Protein inferred from homologyi

Functioni

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

Pathway:ippGpp biosynthesis

This protein is involved in step 1 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), Guanosine-5'-triphosphate,3'-diphosphate pyrophosphatase (gppA)
  2. no protein annotated in this organism
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.
