Figure 4. Interfaces between domains III, IV and V of EF-G and the ribosome in the PRE and the POST complexes.
(A) Overview of the ribosome showing the orientation of the insets B and C. Elements of the ribosome are indicated and colored differently.
(B and C) Positions of domains III (B) and IV (C) on the ribosome in the two complex structures.
(D) Surroundings of domain V in the two complex structures. Helix 43/44, L11-NTD in the stalk base (Sb), Helix 89 and the sarcin-ricin loop (SRL) are shown in yellow in the POST complex and pink in the PRE complex. The L11-NTD in the PRE complex is not visible.
