rDock (previously RiboDock) software download, is an open-source molecular docking software in chemistry that be used for docking small molecules against proteins and nucleic acids. It is primarily designed for high-throughput virtual screening and prediction of binding mode.
rDock is a fast and versatile Open-Source docking program that can be used to dock small molecules against proteins and nucleic acids. It is designed for High Throughput Virtual Screening (HTVS) campaigns and Binding Mode prediction studies.
Key features of rDock software
Docking Preparation: Define cavities using known binders or with user-supplied 3D coordinates. Allow -OH and -NH2 receptor side chains to rotate. Add explicit solvent molecules and structural waters. Supply pharmacophoric restraints as a bias to guide docking.
Pre-Processing of input files: Define common ligand structure for performing tethered docking (requires OpenBabel python bindings). Sort, filter or split ligand files for facilitating parallelization. Find HTVS protocol for optimizing calculation time. Pre-calculate grids to decrease subsequent calculation times.
Post-Processing and Analysis of results: Summarize results in a tabular format. Sort, filter, merge or split results files. Calculate RMSD with a reference structure taking into account internal symmetries (requires OpenBabel python bindings).
Binding Mode Prediction: Predict how a ligand will bind to a given molecule. The ASTEX non-redundant test set for proteins and DOCK and rDock test sets for RNA have been used for validating and comparing rDock with other programs.
HTVS: Run for millions of compounds in short time by exploiting the capabilities of computer calculation farms. Ease of parallelization in relatively unlimited CPUs to optimize HTVS running times. The DUD set has been used for validating rDock and comparing its performance to other reference docking programs.
