Figure Lengend Snippet: (A) B factors derived from normal mode analysis (NMA) showing intrinsically flexible regions of the 5‐HT3A subunit (black line), highlighting the segment between residues 332–333. (B) RMS mobility profiles per residue (RMS mean) of the 5‐HT3A/IRPN (green) and 5‐HT3A/IRPL (red) complexes, indicating that both ligands stabilize the receptor in a similar manner, with greater local fluctuations concentrated in the distal domain (residues 302–349). (C, D) Convergence of the morphing trajectory for the two complexes, monitored by the RMSD of Cα atoms throughout the iterations. (C) The 5‐HT3A/IRPN complex converged to a final RMSD of 1.49 Å in ∼1.35 × 10 4 iterations, while the (D) 5‐HT3A/IRPL complex converged to 1.48 Å in ∼1.45 × 10 4 iterations.
Article Snippet: Molecular dynamics (MD) simulations were conducted using the normal mode analysis (NMA) module to observe the deformability of the ligand–receptor complex that the compounds form when binding to the 5‐HT3A receptor.
