Mutations in domain IV of elongation factor EF-G confer -1 frameshifting.
Title: Mutations in domain IV of elongation factor EF-G confer -1 frameshifting.
The cells with high EFG/RRF (or low RRF/EFG) ratios are more susceptible to fusidic acid than those with low EFG/RRF (or high RRF/EFG) ratios.
Title: Antimicrobial activity of fusidic acid in Escherichia coli is dependent on the relative levels of ribosome recycling factor and elongation factor G.
the CyaA(N600Y) mutant has a transcriptome indicative of increased CRP activity, pointing to an unknown role for CyaA and / or cAMP in gene expression..We show that the large scale transcriptomic changes in the topoisomerase I (FusA(A608E)-TopA(S180L)) mutant likely result from increased negative supercoiling in the cell.
Title: Modulation of Global Transcriptional Regulatory Networks as a Strategy for Increasing Kanamycin Resistance of the Translational Elongation Factor-G Mutants in Escherichia coli.
Kinetics of spontaneous and EF-G-accelerated rotation of ribosomal subunits has been presented.
Title: Kinetics of Spontaneous and EF-G-Accelerated Rotation of Ribosomal Subunits.
Ribosome recycling after peptide chain termination is a special case of the general RRF and EF-G function, which happens whenever fMet-tRNA is not available for triggering 70S scanning.
Title: The Termination Phase in Protein Synthesis is not Obligatorily Followed by the RRF/EF-G-Dependent Recycling Phase.
These results show that EF-G bound to GTP (EF-G-GTP) continuously samples both rotational states of the ribosome, binding with higher affinity to the rotated state.
Title: Coordinated conformational and compositional dynamics drive ribosome translocation.
These structures suggest that EF-G controls the translocation reaction by cycles of conformational rigidity and relaxation before and after GTP hydrolysis.
Title: Control of ribosomal subunit rotation by elongation factor G.
cryo-electron microscopy reconstruction of a fusidic-acid-stalled ribosomal 70S-tmRNA-SmpB-EF-G complex (carrying both of the large ligands, that is, EF-G and tmRNA) at 8.3 A resolution
Title: The complex of tmRNA-SmpB and EF-G on translocating ribosomes.
A central interdomain protein joint in elongation factor G regulates antibiotic sensitivity, GTP hydrolysis, and ribosome translocation
Title: A central interdomain protein joint in elongation factor G regulates antibiotic sensitivity, GTP hydrolysis, and ribosome translocation.
Collectively, the results support a central role of sw1 in driving the EF-G cycle during protein synthesis.
Title: Conformational changes in switch I of EF-G drive its directional cycling on and off the ribosome.
