Figure 2.
Fig. 2. (a) Conformational changes upon GDP and GTP binding.
Conformations of the P-loop in nucleotide-free, GDP-bound and
Gpp(NH)p-bound^7 forms. The nucleotide-free form is shown in
red, the GDP form is shown in dark blue and the Gpp(NH)p form is
shown in light blue. (b) Conformations of switch 2 in
nucleotide-free, GDP-bound and Gpp(NH)p-bound^7 forms. The color
scheme is the same as that described in (a).
