Probability of contact formation between CaM and CaMKII along the binding route. (A), (B) and (C) represent the contact maps calculated between the amino acids from the side-chain of CaM and CaMKII, at the different values of Z̄ ~0.2, 0.3 and 0.6 (as indicated in Fig. 3(B)), respectively. A linearized model of CaM is shown below the plots with the individual helices displayed as cylinders, the linkers connecting the helices shown as lines, and the N-terminal and C-terminal helices are shown in red and blue, respectively.
