Figure 5. Stereo view of the interface between domain 1 and domain 3. The switch I and II regions are shown in yellow and green, respectively. The rest of the poly- peptide chain in domain 1 is shown in purple, and that of the domain 3 in slate blue. Hydrogen bonds are shown as broken lines, and water molecules as cyan spheres. Residues involved in interactions between domains 1 and 3 are shown as ball-and-stick. (a) EC-EF- Tu-GDP; (b) TA-EF-Tu-GTP.
