How to Use MakeDOCK

  • MakeDOCK automates the process of sphere and grid generation for a target.

Input file to MakeDOCK

  • The following files are required to specify the target for MakeDOCK:
  1. rec.pdb: Prepared receptor file
  2. xtal-lig.mol2 (or .pdb): Ligand specification file

Receptor Preparation

To prepare a typical pdb structure for receptor use in MakeDOCK, perform the following steps:

  1. Remove solvent (i.e. crystallographic waters)
  2. Remove other non-essential hetero-atoms (everything but perhaps a co-factor essential for ligand binding)
  3. Remove the ligand itself
  4. Delete all hydrogen atoms
  5. Save as rec_original.pdb
