Amide N-H bond local motions in MD simulations. For each snapshot in all simulations, the orientation of the selected residue N-H amide bond (in the local reference frame used for M₁ and M₂) is plotted on a cylindrical map projection (latitude (ϕ) versus longitude (Λ)). Isolines follow vector orientation density in rad⁻²ns⁻¹; they are: 50, 100, 200, and 400. Mean orientation is centered at the origin.
