FIGURE 9.

Conformation of the L11–rRNA complex in the factor-released state. (A) Cryo-EM map of the 70S ribosome (30S: yellow, 50S: blue) in the factor-released state with tRNA in the A site (pale pink). The boxed region includes the GAC. (B) Enlarged view of the boxed GAC in A. (C) Stereo-view of MDI fitted into the cryo-EM map. (D) Stereo-view of MDII fitted into the map. (E) Stereo-view of fitting of the crystal structure of the L11–rRNA complex fitted into the same cryo-EM map as shown in C and D. In C, D, and E, the cryo-EM maps are rendered semitransparent for a better view of the fitting positions.
