General annotation (Comments)

Function

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 By similarity. HAMAP-Rule MF_01550

Catalytic activity

Guanosine 5'-triphosphate,3'-diphosphate + H2O = guanosine 3',5'-bis(diphosphate) + phosphate. HAMAP-Rule MF_01550

Pathway

Purine metabolism; ppGpp biosynthesis; ppGpp from GTP: step 1/2. HAMAP-Rule MF_01550

Sequence similarities

Belongs to the GppA/Ppx family. GppA subfamily.
