Molecular docking with protein backbone flexibility is one of the hardest problems in the area of Computational Biology. Due to the complex and various interactions within the protein and with the ligand, simplifications are needed to compute the final docking complex in a time-efficient manner. The Anisotropic Network Model (ANM) has proven to be an effective tool to determine the most significant protein backbone motions that are relevant for docking. By comparing to a recently published approach, we present our own ideas towards an ANM docking method that resembles molecular dynamics simulations to model the process of backbone rearrangement upon ligand binding.
