Figure 4. Flexibility in FGF1 as determined by molecular dynamics simulations.
(A) Time evolution of Cα atom RMSD. (B) Cα atom root-mean-squared-fluctuation about time-averaged positions for the 20 ns to 200 ns interval. Data are shown for the five WT FGF1 (red) and five P135G FGF1 (green) trajectories. Values were computed after least-squares alignment of all Cα atoms relative to the starting crystallographic conformation.
