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}.
