Extended Data Fig. 4: Boltzmann modelling of filament segment curvature distributions.
From: Bending forces and nucleotide state jointly regulate F-actin structure
a, Curvature distributions (left column) of ADP–F-actin (top) and ADP–Pi-F-actin (bottom) with modelled thermal bending probability distributions. Residual plots (right column) between the measured and theoretical distributions. Grey curves correspond to adjusted bending models fit with a multiplicative parameter in the energy term. b, Theoretical probability distributions of 500 Å elastic rods bending due to thermal fluctuations, modelled as Boltzmann distributions. Varying the persistence length between 5 μm and 15 μm demonstrates the effect of filament bending stiffness.
