The graph shows the RMSD of the backbone atoms of a protein-drug complex over time for a molecular dynamics simulation using NAMD. The RMSD initially increases over time, then reaches a plateau. This suggests that the protein-drug complex is initially unfolding, but then reaches a stable configuration. The plateau in the RMSD suggests that the protein-drug complex is now at its equilibrium state. The graph shows that the bend energy decreases over time. This indicates that the molecule is becoming more relaxed and less bent. The bend energy reaches a plateau at around 5000 time steps. This suggests that the molecule has reached a stable configuration.
