2020 DOCK tutorial 2 with PDBID XXXX

I. Introduction

DOCKING

DOCK, a commonly used computational tool used to sample a library of small molecules, ligands and attempts to successfully dock these within their target site, typically a rigid protein into their most energetically favorable positions. To accomplish this, first DOCK uses a global search of the entire protein to determine which locations will be the most energetically favorable, which will be the anchors. Following this, these ligands will take on a variety of different geometric poses to obtain the most conformationally favorable ligand positions. This software is commonly used to perform the hit to lead process in drug discovery to narrow down the drug possibilities from up to hundreds of millions to a few hundred. The drug discovery process then continues using this framework to further select and refine the potential drug candidates.

2GQG

This rigid protein is of the ABL Kinase Domain with the ligand being Dasatinib. This structure was identified using X-ray crystallography with a 2.4A resolution, lower resolutions are preferred.

Directories

For this part of the experiment, create an initial directory in your linux operating systems to work on your experiment

          mkdir 2GQG_Experiment

Following this change the directory to this directory

          cd 2GQG_Experiment

Use the mkdir command in your linux operating system to make all these directories to store your files for the experiment

          00.files
          01.dock_prep
          02.surface_spheres
          03.grid_box
          04.dock
          05.footprint
