- | During tRNA translocation on the ribosome, an arc-like connection (ALC) is formed between the G' domain of elongation factor G (EF-G) and the L7/L12-stalk base of the large ribosomal subunit in the GDP state. To delineate the boundary of EF-G within the ALC, we tagged an amino acid residue near the tip of the G' domain of EF-G with undecagold, which was then visualized with three-dimensional cryo-electron microscopy (cryo-EM). Two distinct positions for the undecagold, observed in the GTP-state and GDP-state cryo-EM maps of the ribosome bound EF-G, allowed us to determine the movement of the labeled amino acid. Molecular analyses of the cryo-EM maps show: (1) that three structural components, the N-terminal domain of ribosomal protein L11, the C-terminal domain of ribosomal protein L7/L12, and the G' domain of EF-G, participate in formation of the ALC; and (2) that both EF-G and the ribosomal protein L7/L12 undergo large conformational changes to form the ALC. | ||
