Chemical versus mechanical perturbations on the protonation state of arginine in complex lipid membranes: insights from microscopic pKa calculations.


Charged amino acids such as Arginine play important roles in many membrane-mediated biological processes such as voltage gating of ion channels and membrane translocation of cell penetration peptides. It is well established that local membrane deformation and formation of water defects are crucial to the stabilization of charged species in contact with the… (More)
