2D-PMF computed at (A) AM1/MM; (B) RM1/MM; (C) AM1:M06-2X/MM; and (D) RM1:M06-2X/MM levels. Averaged values of the structures obtained along the corresponding 1D PMFs displayed in Fig. 1 are shown as circles in panels A and B. Distances of axes are in Å while values on isoenergetic lines are in kcal·mol−1. Surfaces computed at 293 K.
