Virtual screening with AutoDock VINA Three sets of compounds were considered for the virtual screening on three proteins (spike protein, nucleocapsid protein, and 2’-o-ribose methyltransferase). Software Docking results Table containing the docking result(s) We should note that molecular docking software is currently under constant development and improvement. Then, the highly precise docking simulations for the resulting compounds using Docking Study module program are useful for obtaining a drug candidate. Furthermore, if the most of the calculated average RMSD for a specific target is high and/or self-docking RMSDs are also high, it can indicate poor performance of Autodock Vina on a specific target and vice versa. ViewDockfacilitates the interactive analysis of receptor-ligand docking results. To analyze vina results in ADT (1. See example 2. & Olson, A. And the target prediction accuracy of AutoDock Vina only increases slightly after score normalization with 15 cocrystallized proteins moving up and 21 cocrystallized proteins dropping in 45 reverse docking cases. Further speed-up is achieved from parallelism, by using multithreading on multi-core machines. These generally deteriorated with the peptides getting longer and thus losing their small-molecule character [ 9 ], a common observation in PPeD. site3, vina. In AutoDock Vina the grid resolution is internally assigned to 1Å. The best docking pose per molecule according to the lowest docking score of Vina thus was selected and was adopted for inter-molecular GOLD uses force-field-based scoring functions , while AutoDock Vina uses its own hybrid scoring function . The performance was compared in the original publication, and on average, AutoDock Vina did considerably better, both in speed and accuracy. Protein structure of caspase-3 (3DEI) and caspase-8 (3KJQ) was obtained from the protein data bank and docked with selected triterpenoids using AutoDock Tools and AutoDock Vina. J.
