The protein conformation (represented by its C_α coordinates) from each frame in the simulation trajectories was aligned against the crystal structure, and the mean conformation for each simulation was obtained by averaging the aligned C coordinates over the frames in the last 40 ns of the simulation. These mean conformations were compared to the open (4AKE) [7] and the closed (1AKE) [6] AdK crystal structures, with the RMSDs provided in the table.
