Binding Orientations and Lipid Interactions of Human Amylin at Zwitterionic and Anionic Lipid Bilayers

Table 1

Membrane binding orientations of hIAPP monomer at POPC bilayer. Our MD runs start from four different initial states S(0), S(90), S(180), and S(270). For each initial state, there are three independent 120 ns MD runs, and the final binding orientations are identified using the data of last 20 ns. According to the residues binding to the bilayer surface, four different binding orientations are identified and they are named as Fa, Fb, Fc, and Fd. These four binding orientations are given in Figure 4.
