CC -!- FUNCTION: Catalyzes the conversion of pppGpp to ppGpp. Guanosine
CC pentaphosphate (pppGpp) is a cytoplasmic signaling molecule which
CC together with ppGpp controls the 'stringent response', an adaptive
CC process that allows bacteria to respond to amino acid starvation,
CC resulting in the coordinated regulation of numerous cellular
CC activities. {ECO:0000255|HAMAP-Rule:MF_01550}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=guanosine 3'-diphosphate 5'-triphosphate + H2O = guanosine
CC 3',5'-bis(diphosphate) + H(+) + phosphate; Xref=Rhea:RHEA:13073,
CC ChEBI:CHEBI:15377, ChEBI:CHEBI:15378, ChEBI:CHEBI:43474,
CC ChEBI:CHEBI:77828, ChEBI:CHEBI:142410; EC=3.6.1.40;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_01550};
CC -!- PATHWAY: Purine metabolism; ppGpp biosynthesis; ppGpp from GTP: step
CC 2/2. {ECO:0000255|HAMAP-Rule:MF_01550}.
CC -!- SIMILARITY: Belongs to the GppA/Ppx family. GppA subfamily.
CC {ECO:0000255|HAMAP-Rule:MF_01550}.
