Distribution of conservation scores for protein 2B6F (PDB ID) related to the three steps. (A) distribution of scores in the standard PSSM, (B) distribution of scores in the masked and filtered PSSM, and (C) distribution of scores in the smoothed PSSM. The red dotted rectangles mark the position of ATP-binding residues (only residues 51~121 in the A chain are displayed).
