Figure 3.
Interaction (marked with an asterisk) between His-19 in the P loop of EF-Tu (green) and A2260 in the tetraloop of the SRL (cyan; tetraloop shown in blue). This interaction presumably establishes an anchor point holding one of the wings of the hydrophobic gate (compare Fig. 2) in place. (Inset) The ribosome is shown in the same orientation. The map is contoured at 2.5 σ. This figure is rotated 90° with respect to the view in Fig. 2.
