Protein existenceInferred from homology

General annotation (Comments)

Function

An essential GTPase which binds GTP, GDP and possibly (p)ppGpp with moderate affinity, with high nucleotide exchange rates and a fairly low GTP hydrolysis rate By similarity. It may play a role in control of the cell cycle, stress response, ribosome biogenesis and in those bacteria that undergo differentiation, in morphogenesis control Potential. HAMAP-Rule MF_01454

Cofactor

Magnesium Potential.

Subunit structure

Monomer By similarity.

Subcellular location

Cytoplasm By similarity.

Sequence similarities

Belongs to the GTP1/OBG family.

Contains 1 G (guanine nucleotide-binding) domain.
