Protein

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

Gene

gppA

Organism
Escherichia coli
Status
Unreviewed-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 annotationSAAS annotation

Catalytic activityi

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

Pathwayi: ppGpp biosynthesis

This protein is involved in step 2 of the subpathway that synthesizes ppGpp from GTP.UniRule annotationSAAS annotation
