Mobility of complex salt bridges between cytochrome c and Apaf-1 in the course of MD simulations. Conformations of particular complex salt bridges observed in MD simulation were superimposed individually for each group of contacts. Protein backbone fragments are shown in cartoon representations: cytochrome c in cyan, Apaf-1 in magenta. Interacting residues are shown in stick representation: lysine residues in blue, aspartate and glutamate residues in red
