Figure 4. Stereoview of ATP in complex with the interdomain hinge region of CAPK. AMPPNP and GMPPNP as bound to rmCK2 are drawn in black (AMPPNP) and gray (GMPPNP) after three-dimensional fitting of the corresponding protein matrices to that of CAPK. Mn^2+ (green) and Mg^2+ (black in complex with AMPPNP, gray in complex with GMPPNP) are drawn as balls. Some important hydrogen bonds are marked as magenta dotted lines with distances given in Å.
