The “exact” PMF using 33 windows is shown for comparison (b, dotted line). DG for the overall proton transfer PMF (dotted line in Figure 1b); however, analytical integration of only seven FEP windows (instead of the usual 30 win­ dows) can also accurately yield the full PMF (solid line in Figure 1b). 5 kcal/mol was found relative to the traditional PMF method when employing this polynomial quadrature method. Additionally, the 2-D PMF simulations carried out in the FAAH study always involved a proton transfer as one of the reaction coordinates, allowing the use of this cubic poly­ nomial quadrature method in at least one direction.

However, the challenge is to obtain a reliable estimate for complex molecular systems within a reasonable allocation of computer time and resources [1—7]. Adequate sampling of regions that substan­ tially contribute to the free energy of fluidic systems and flexible macromolecules has proven to be especially difficult computationally [8—11]; yet, such systems are generally of interest in many organic and biochemical enzymatic studies [12—15]. Multiple successful approaches have been reported for computing free-energy surfaces [16—20], but of specific interest to this work is the free-energy perturba­ tion (FEP) technique that utilizes the Zwanzig expression (Eq.
