Figure 1. Dynamics in calmodulin binding. The linker of
calmodulin (white) bends as the ends of the protein engulf the
target (red stick model); there are also significant motions
within the globular ends. Experiments to characterize these
motions are necessary to understand how calmodulin works (see
text for details). Within the globular ends, helices are shown
in cyan, b strands in green and loops in orange; Ca^2+ ions are
depicted as white spheres. (The figure was made using the
program RIBBONS [41].)
