PMF between the tethered head of kinesin and the MT surface for λ = 1. (A) A structure of kinesin when λ = 1, with a yellow arrow depicting the accessible search space. (B) 1D PMFs in x, y, and z projections are shown at various temperatures. (C) 2D PMFs in xz, yz, and xy projections at T = 295 K. Binding sites e and d and entropic basin S are marked with circles and arrows. (D) 2D PMFs at T = 355 K. The energy scale is color-coded in the kBT unit from dark brown to white in C and D.
