CC   -!- FUNCTION: An essential GTPase which binds GTP, GDP and possibly
CC       (p)ppGpp with moderate affinity, with high nucleotide exchange rates
CC       and a fairly low GTP hydrolysis rate. Plays a role in control of the
CC       cell cycle, stress response, ribosome biogenesis and in those bacteria
CC       that undergo differentiation, in morphogenesis control.
CC       {ECO:0000255|HAMAP-Rule:MF_01454}.
CC   -!- COFACTOR:
CC       Name=Mg(2+); Xref=ChEBI:CHEBI:18420;
CC         Evidence={ECO:0000255|HAMAP-Rule:MF_01454};
CC   -!- SUBUNIT: Monomer. {ECO:0000255|HAMAP-Rule:MF_01454}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_01454}.
CC   -!- SIMILARITY: Belongs to the TRAFAC class OBG-HflX-like GTPase
CC       superfamily. OBG GTPase family. {ECO:0000255|HAMAP-Rule:MF_01454}.
