'''The crystal structure of the B. subtilis YphC GTPase in complex with GDP'''<br />


==Overview==
==The crystal structure of the B. subtilis YphC GTPase in complex with GDP==
The structure of a Bacillus subtilis YphC/GDP complex shows that it, contains two GTPase domains that pack against a central domain whose fold, resembles that of an RNA binding KH-domain. Comparisons of this structure, to that of a homologue in Thermotoga maritima reveals a dramatic, rearrangement in the position of the N-terminal GTPase domain with a shift, of up to 60 A and the formation of a totally different interface to the, central domain. This rearrangement appears to be triggered by, conformational changes of the switch II region in this domain in response, to nucleotide binding. Modeling studies suggest that this motion, represents transitions between the "on" and "off" states of the GTPase, the effect of which is to alternately expose and bury a positively charged, face of the central domain that we suggest is involved in RNA recognition, as part of the possible role of this enzyme in ribosome binding.
