Figure 4.

Dipole moment vectors for WT and mutant peptides in the normal membrane-bound state. Arrows indicate the dipole moment vectors calculated for representative WT and mutant peptides bound to the POPC bilayer in the AT simulations. Note that the maximum angle is shown; i.e., the peptides were rotated around the z-axis, such that the arrows aligned onto the xz-plane. The starting point of each vector represents the time-averaged position (depth) of the COM from the AT simulations.
