| - | The crystal structure of elongation factor 1alpha from the archaeon Sulfolobus solfataricus in complex with GDP (SsEF-1alpha.GDP) at 1.8 A resolution is reported. As already known for the eubacterial elongation factor Tu, the SsEF-1alpha.GDP structure consists of three different structural domains. Surprisingly, the analysis of the GDP-binding site reveals that the nucleotide- protein interactions are not mediated by Mg(2+). Furthermore, the residues that usually co-ordinate Mg(2+) through water molecules in the GTP-binding proteins, though conserved in SsEF-1alpha, are located quite far from the binding site. [(3)H]GDP binding experiments confirm that Mg(2+) has only a marginal effect on the nucleotide exchange reaction of SsEF-1alpha, although essential to GTPase activity elicited by SsEF-1alpha. Finally, structural comparisons of SsEF- 1alpha.GDP with yeast EF-1alpha in complex with the nucleotide exchange factor EF-1beta shows that a dramatic rearrangement of the overall structure of EF-1alpha occurs during the nucleotide exchange. | ||
