Protein structural flexibility. (A) The maximum RMSD and equivalent minimum TM-score of the structural groups. The red rectangles and purple diamonds represent the base 2 logs of the structural numbers in structural groups with (blue dots) or without mutations (green triangles), respectively. (B) Structural comparison of PDB: 1U1D: A (red)  and PDB: 1K3F: F (green) .
