(A) RMSF value for each residue during MD simulations. Flexible domains are highlighted in green rectangles. (B) The structure colored by the RMSF value. Highly flexible domains such as N-term and H8 were removed for clarity. (C) The movement expressed by major PCs. Yellow, green, and blue arrows represent the movement shown by PC1, PC2, and PC3, respectively.
