Charges were calculated based on the protocol by Duan, Y. et al. A point-charge force field for molecular mechanics simulations of proteins based on condensed-phase quantum mechanical calculations. J. Comput. Chem. 24, 1999–2012 (2003). Missing bonded parameters were adopted from GAFF2. *** Converted to GROMACS from amber format using the ParmEd tool (https://github.com/ParmEd/ParmEd) HFD-bound: contains the directories for each simulation repeat listed in the table of simulations. 1, 2, and 3: simulations that were started by replacing the terminal actins with HFD-bound actins. 1' and 2': simulations that were started by docking HFD after some simulation without HFD (see below HFD-free simulations 1 and 2) HFD-free: contains the directories for each simulation repeat listed in the table of simulations. 1, 2, and 3: simulations of the cofilin-decorated actin filament. 2': simulations that was started by removing HFD from the HFD-bound system (see above HFD-bound simulation 2) Each subdirectory (under 1 2 3, etc.) contains prod.mdp: simulation setting file topol.top: GROMACS topology file t0.pdb: initial coordinates for simulation obtained after a set of restrained NVT and NpT equilibration steps prod0.tpr: the GROMACS tpr file index.ndx: index file nW.pdb: t0.pdb with all water molecules removed nW.xtc: the simulation trajectory with all water molecules removed. _FORCEFIELD: link to ../../_FORCEFIELD
