What Scoring does AutoDock Vina use?

For the estimation of ligand-receptor affinity, Vina uses an empirical scoring function which is inspired by the X-score function [7]. As stated by the authors, the nature of the scoring function is “more of a machine learning than a physics-based function” [3].

How do I use AutoDock Vina docking?

Preparation of .pdbqt files

1. Open AutoDock Vina, click “File” –> click “Read Molecule” –> select protein.
2. We will delete water molecules from the protein as they can make unnecessary bonds with the ligand.
3. We will add polar hydrogens in order to avoid any empty group/ atom left in the protein.
4. We will save this file as .

How accurate is AutoDock?

In the present study, based on an extensive dataset of 2002 protein–ligand complexes from the PDBbind database (version 2014), the performance of ten docking programs, including five commercial programs (LigandFit, Glide, GOLD, MOE Dock, and Surflex-Dock) and five academic programs (AutoDock, AutoDock Vina, LeDock.

What does AutoDock Vina do?

AutoDock Vina, a new program for molecular docking and virtual screening, has been presented. Vina uses a sophisticated gradient optimization method in its local optimization procedure. The calculation of the gradient effectively gives the optimization algorithm a ”sense of direction” from a single evaluation.

How do you cite AutoDock Vina?

What are docking results?

Docking is one of the most commonly used techniques in drug design. It is used for both identifying correct poses of a ligand in the binding site of a protein as well as for the estimation of the strength of protein-ligand interaction. Therefore, docking results have to be verified by subsequent in vitro studies.

What is the difference between Autodock and Autodock Vina?

The major difference is the scoring function. In Autodock 4 the scoring function is based on the AMBER force field and in Autodock Vina it is a hybrid scoring function (empirical + knowledge-based) based on the X-Score function with some different parameters which is not published at the moment.

Which is better AutoDock or AutoDock Vina?

Autodock Vina is much faster and more accurate (depending on the system). It calculates the grid charges internally and setting up the docking is much easier. More accurate charge calculations can lead to better docking results but they are more computationally expensive. Autodock Vina ignores user supplied charges.
