CC   -!- FUNCTION: In eubacteria ppGpp (guanosine 3'-diphosphate 5'-diphosphate)
CC       is a mediator of the stringent response that coordinates a variety of
CC       cellular activities in response to changes in nutritional abundance.
CC       This enzyme catalyzes the formation of pppGpp which is then hydrolyzed
CC       to form ppGpp (By similarity). {ECO:0000250}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=ATP + GTP = AMP + guanosine 3'-diphosphate 5'-triphosphate;
CC         Xref=Rhea:RHEA:22088, ChEBI:CHEBI:30616, ChEBI:CHEBI:37565,
CC         ChEBI:CHEBI:142410, ChEBI:CHEBI:456215; EC=2.7.6.5;
CC   -!- PATHWAY: Purine metabolism; ppGpp biosynthesis; ppGpp from GTP: step
CC       1/2.
CC   -!- SIMILARITY: Belongs to the RelA/SpoT family. {ECO:0000305}.
