Protein

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

Gene

gppA

Organism
Erwinia tasmaniensis (strain DSM 17950 / Et1/99)
Status
Reviewed-Annotation score: Annotation score: 3 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
