Cloned (Comment) | Organism |
---|---|
gene fusA, recombinant expression of the N-terminal domain (74 residues) of Thermus thermophilus ribosomal protein L9 fused to the N-terminus of EF-G connecting residues 1-74 of ribosomal protein L9 and residues 8-691 of EF-G in Escherichia coli strain BL21(DE3) Star | Thermus thermophilus |
Crystallization (Comment) | Organism |
---|---|
purified ribosomal protein L9-elongation factor G fusion protein in complex with GDP, the EF-G-GTP complex is bound on a pre-translocation ribosome (PRE ribosome) that is deficient in tRNA translocation upon EF-G binding, sitting drop vapour diffusion method, mixing of 0.1 mM protein in 10 mM Tris-HCl, pH 7.5, 200 mM KCl, 10 mM Mg(CH3COO)2, and 1 mM 2-mercaptoethanol, with X-ray diffraction structure determination and analysis at 2.0 A resolution. Only in the presence of the GDP nucleotide, and not GTP, does EF-G crystalize with the non-rotated ribosome under the experimental conditions | Thermus thermophilus |
