Molecular docking (Zdockpro in Insight II): • Zdock is a rigid-body, initial stage protein-protein docking algorithm that applies the ligand rotation and the shape complementarity method through the Fast Fourier Transform method (FFT). The ZDOCK scoring function in this release is based on pairwise shape complementarity (PSC). • Rdock is based on the CHARMm simulations program and is usedfor further refinement of poses generated by ZDOCK. It also ranks the docked structures based on the CHARMm electrostatic interaction energy and ACE desolvation energy. Result filtration • Known key amino acid included in or excluded from the resultant interface • Known interaction force: hydrophobic, salt,…
