Association of wild-type helices characterized by the one-dimensional PMF as a function of the interhelical distance (COM) at different times (top panel, analyzed on time windows of 100 ns each). The correlations between the rotation of helix B relative to A (β, middle panel), and the rotation of helix B around its helical axis (ϕ, bottom panel) as a function of interhelical distance, are shown for t = 500 ns only to distinguish the distinct states in the PMF profile.
