CC -!- FUNCTION: Functions as a (p)ppGpp synthase. In eubacteria ppGpp
CC (guanosine 3'-diphosphate 5'-diphosphate) is a mediator of the
CC stringent response that coordinates a variety of cellular activities in
CC response to changes in nutritional abundance. It is necessary for
CC persistence in mice, essential for intracellular growth of Brucella and
CC required for expression of the type IV secretion system VirB and
CC therefore plays a role in adaptation of Brucella to its intracellular
CC host environment. {ECO:0000269|PubMed:16803581}.
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 -!- DISRUPTION PHENOTYPE: Cells show morphological abnormalities such as
CC branching and swelling forms during vegetative growth. It is unable to
CC persist during stationary phase, presumably because of nutrient
CC limitation occurring during this growth phase. It shows an important
CC growth defect in human HeLa cells and in ovine macrophages MOCL3. At
CC four weeks post infection the number of viable bacteria (deletion
CC mutant) in mouse spleen is markedly reduced compared to the wild-type.
CC The deletion mutant shows very low levels or absence of VirB at all
CC time points of growth. {ECO:0000269|PubMed:16803581}.
CC -!- SIMILARITY: Belongs to the RelA/SpoT family. {ECO:0000305}.
