Protein attributes

Sequence length	341 AA.
Sequence status	Complete.
Protein existence	Inferred 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. HAMAP-Rule MF_01454
Subcellular location	Cytoplasm By similarity HAMAP-Rule MF_01454.
Sequence similarities	Belongs to the GTP1/OBG family. Contains 1 G (guanine nucleotide-binding) domain.
Sequence caution	The sequence AAL51388.1 differs from that shown. Reason: Erroneous initiation.
