Protein S4 is near the elongation factor G binding site in the ribosome.
Using a mild iodination method for protein radioactive labeling, it has been shown that elongation factor G, when bound to the ribosome as EFG-GDP-fusidic acid complex, protects protein S4 from labeling. The results indicate that protein S4 is probably near the ribosomal EFG binding site.
