A predicted GTP-binding protein from the hyperthermophilic archaeon Sulfolobus solfataricus, termed SsGBP, has been cloned and overexpressed in Escherichia coli. The purified protein was crystallized using the hanging-drop vapour-diffusion technique in the presence of 0.05 M cadmium sulfate and 0.8 M sodium acetate pH 7.5. A single-wavelength anomalous dispersion data set was collected to a maximum resolution of 2.0 Å using a single cadmium-incorporated crystal. The crystal form belongs to space group P212121, with approximate unit-cell parameters a = 65.0, b = 72.6, c = 95.9 Å and with a monomer in the asymmetric unit.
