The change in minimum energy for side chain–side chain contacts as a result of training the scoring function E 86 for (a) enzyme/inhibitor, (b) antigen/antibody, and (c) other complexes. Blue values mean the interaction became more attractive, red means the interaction became more repulsive. Note the different energy scales for the protein classes
