Figure 1.
Figure 1. Ribbon diagrams of EF-Tu molecules.
(a) EC-EF-Tu-GDP; (b) same view of EF-Tu-GTP from
T. aquaticus (TA-EF-Tu-GTP). The switch I region is
shown in yellow and the switch II region in green. The
rest of the polypeptide backbone is shown in purple,
royal blue and dark blue for domain 1 (residues 8-204),
domain 2 (residues 205-298) and domain 3 (299-393),
respectively. GDP or GTP molecules are shown in ball-
and-stick models, and Mg
2+
are shown as cyan spheres.
The Figure was drawn with MOLSCRIPT (Kraulis,
1991), as are Figures 4 and 5.
