A comparison of some dynamic properties of HP1α-H3K9me without and with phosphorylation modifications (serine residues: 11–14). (A) RMSD of original (phos-NCD- H3K9me, left) and modified structure (unmod-NCD- H3K9me, right) during equilibrium MD trajectories. (B) RMSF of phos-NCD-H3K9me (blue line) and unmod-NCD-H3K9me (red line) during equilibrium stage. (C) Dynamic secondary structures of phos-NCD-H3K9me (left) and phos-NCD-H3K9me (right).
