Interactions that stabilize residues in the membrane. (A and B) Membrane deformation induced by the presence of arginine at the center for (A) OmpLA:Arg²¹⁰ and (B) PolyL:Arg. The protein is colored as in Fig. 1 with arginine shown in a stick representation colored by atom type. The DLPC bilayer is drawn as in Fig. 1. Water is shown as a continuous gray surface above and below the membrane, while water molecules that penetrate the bilayer are shown in a licorice representation. (C) Hydrogen-bonding of Ser²¹⁰ to the OmpLA β-barrel backbone.
