Figure 3. The NMR structure of Ca^2+-bound CaM in complex with GADp. (a) Stereo-view of the superposition of 20 energy-minimized structures. The view is along the axis of GAD peptide A. CaM helices are in blue, strands in cyan and calcium ions in yellow. Peptide helices are in magenta. (b) Representative structure of the 20 structures illustrated in (a). (c) Same structure rotated to illustrate its pseudo-symmetric orientation. Calcium ions are indicated with roman numerals.
