Structures are the point of contact or before breaking from MD simulations. Representative configurations obtained from MD simulations right before contact or right before breaking are shown. (A) dimer, (B) monomer, (C) double contact dimeric transversal, (D) double contact dimeric parallel and (E) double contact monomeric.
