Figure 1.
Fig. 1. (a) Amino acid sequence of aIF2γ from Sso. Residues,
conformations of which are changed in free and GDP forms of
aIF2γ, are boxed. The two conserved regions, which surround the
nucleotide base, are shown in magenta. The P-loop is shown in
green. Switch 1 and switch 2 are shown in brown and blue,
respectively. (b) Stereo representation of one of the two
aIF2γ–GDP molecules. Numbered C^α atoms are shown as gold
spheres. Pyrophosphates are shown in magenta, Gpp(NH)p is shown
in green and GDP is shown in red.
