Surface conservation index of the split pocket in the human mitogen-activated protein kinase (PDB1ouk.A). (a) The split pocket (the 22th pocket) has the highest conservation index (0.703). Catalytic residues {K152, S154, N155} colored in cyan are located on the protein binding surface. (b) The spatial pattern of (a) consists of 26 residues with conservation weights for assessing the degree of evolutionary conservation.
