N2 - Inter-Fragment Interaction Energies (IFIEs) obtained by Fragment Molecular Orbital (FMO) method can quantitatively measure the effective interactions between ligand and residues in protein, which are therefore useful for drug discovery. However, it has not been clarified whether the IFIEs can be reproduced using only geometrical (e.g., interatomic distances) information of biomolecular complex without resort to explicit FMO calculations. In this study, through machine learning technique, we propose a highly accurate reproduction or prediction scheme for ligand-protein IFIEs using only the distance information as descriptors, thereby drastically saving the computational cost in FMO analysis for a variety of conformations.
