How to Dock Metal Complexes in AutoDock 4 | Step-by-Step Tutorial
In this tutorial, I demonstrate how to dock metal complexes in AutoDock 4.2, with a complete step-by-step workflow designed for researchers working with transition metal compounds.
Docking metal-containing complexes presents unique challenges because most docking algorithms are parameterized for organic molecules. In this video, I explain how to properly prepare a metal complex, optimize its geometry using DFT, generate the required files, and successfully perform docking in AutoDock 4.2.
This tutorial is especially useful for researchers working in:
Computational chemistry
Drug discovery
Bioinorganic chemistry
Anticancer metal complex research
Organometallic docking studies
🔬 What You Will Learn
✔ How to prepare the protein target (.pdb → .pdbqt)
✔ How to generate ligand .pdbqt files
✔ How to define the grid box correctly
✔ How to run AutoGrid and AutoDock
✔ How to extract and analyze docking poses
✔ Key challenges in metal docking and how to handle them
⚠ Important Notes
Metal parameterization requires special attention.
Transition metal geometries must be optimized before docking.
Docking scores for metal complexes should be interpreted cautiously
