Figure 2.
Fig. 2. Conformational changes upon nucleotide binding.
Comparison of the Ca[2]-E[1] and Ca[2]-E[1]-AMPPCP forms, based
on the same alignment as in Fig. 1C. Domains occupying similar
positions are shown as colored surfaces with the coordination
spheres of the two calcium ions in blue. The series of
conformational changes leading from ATP binding to Ca^2+
occlusion have been indicated by arrows on the Ca[2]-E[1] form.
The figure was prepared with PyMOL (26).
