    • The limited dynamics of the protein backbone in the beta-barrel has been demonstrated in the experiment, e.g., ref 89, and indirectly, in the theoretical study of ion current through the porin protein in which modeling by the all-atom MD simulation and by Brownian dynamics simulation of ions in the rigid protein gave very similar distributions of ions inside the channel indicating that the dynamics of the protein backbone is unimportant for the dynamics inside the pore. In the current study, we are interested in the dynamics ofthe ligand molecule inside the pore. The β-barrel forms a well-defined barrier to separate the system into two compartments: inside the pore where we attempted to simulate the all-atom dynamics of all species involved in full detail and behind the barrel wall, where simplified constrained dynamics of the model lipid bilayer, protein backbone was employed because the influence of this region onto the dynamics inside the pore is expected to be small.
