MM/PBSA free energies are averages over the last 10 ns of the trajectories (2500 frames).
∗
Adaptation energy (kcal/mol) is calculated by subtracting the energy of the free state from that of the bound state.
†
Bond, angle, dihedral energy.
‡
van der Waals energy.
§
Electrostatic energy.
¶
Contribution of the nonpolar surface area to the solvation free energy.

∗∗
Electrostatic solvation free energy with the GB model.
††
Total energy, sum of all the above energy terms.
