Figure 4.

Field of coarse-grained site-dipoles, d̄_w(r_i,R) (w = 1 ns and R = 2 Å), around amino acids. The site-dipole field was calculated by dividing space into 1 Å cubes. A bar represents the vector of d̄_w(r_i,R). (A) System A with |d̄| ≥ 0.4, (B) system B with |d̄| ≥ 0.4, and (C) system C with |d̄| ≥ 0.3 (see MD simulations for definitions of systems A, B, and C).
