Distribution of ligand binding pocket size. Distances between αC-helix and binding site of conformations sampled during the MD simulations of EGFR WT (green), EGFR L858R (red) and EGFR 19del (black) complexed to (A) afatinib (B) gefitinib (C) erlotinib state. (D) Average number of contacts that various inhibitors make with the alpha C-helix of EGFR WT (green), EGFR L858R (red) and EGFR 19del (black).
