Protein attributes

Sequence length	494 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is not processed.
Protein existence	Inferred from homology.

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.
Catalytic activity	Guanosine 5'-triphosphate,3'-diphosphate + H2O = guanosine 5'-diphosphate,3'-diphosphate + phosphate. HAMAP MF_01550
Pathway	Purine metabolism; ppGpp biosynthesis; ppGpp from GTP: step 1/2. HAMAP MF_01550
Sequence similarities	Belongs to the gppA/ppx family. GppA subfamily.
