Fig. 4: Per-residue interactions with phospholipids and ions.

Atomic models with residues colored according to their interaction frequencies with the acyl chains (green), phosphate group (orange), quaternary choline group (blue), chloride (light green), and sodiums ions (purple) throughout the MD simulations. Residues that interact in at least 50% of all conformations are colored with the color saturation linearly increasing with interaction frequencies between 50 and 100%. The remaining residues are colored white.
