Figure 2. — Illustration of the motion of H38 as the E.c. 70S ribosome undergoes a ratcheting movement, as observed by the cryo-EM studies. (A) The density map of the 70S ribosome in a non-ratcheted state (3,64) (EMDB Access Code: 1056), with the fitting model of H38. The density map of 30S subunit (yellow) is outlined. (B) The density map of the 70S ribosome in a ratcheted state (3) (EMDB Access Code: 1363), with the fitting model of H38. (C) The 50S subunit in the non-ratcheted state. (D) The 50S subunit in the ratcheted state. (E) The 70S density map is re-oriented from the position shown in A, and the H38 model in the ratcheted state is added at the ratcheted position (red). (F) A zoom-in view of the boxed region shown in E. All cryo-EM density maps are shown as transparency.
