Figure 6.

Number density of lipid heavy atoms, n_l(r,z), computed as a function of distance r from the peptide center of mass and distance z from the bilayer midplane at z = 0 Å. Black and red lines mark the boundaries of the lipid bilayer, z_l(r), for the Aβ+BL+Ca and Aβ+BL systems, respectively. The boundaries of the proximal region are represented by dashed vertical lines. The figure shows that calcium enhances thinning of the DMPC bilayer caused by bound Aβ monomer. To see this figure in color, go online.
