5 Mistakes Students Make in Molecular Docking
Molecular docking is more than clicking "Run." The quality of your results depends on the choices you make before the docking even begins.
Here are five common mistakes I see:
1. Choosing the wrong protein structure Not every PDB structure is suitable. Always evaluate resolution, missing residues, mutations, bound ligands, and whether the structure represents the biologically relevant state.
2. Skipping proper protein preparation Removing water molecules blindly, ignoring cofactors, failing to add hydrogens, or not correcting protonation states can significantly affect docking accuracy.
3. Docking every compound without screening Running hundreds or thousands of compounds without first applying filters like Lipinski's Rule of Five, Veber's Rule, and ADMET screening wastes both time and computational resources.
4. Trusting docking scores alone A more negative binding affinity doesn't automatically mean a better drug candidate. Always examine hydrogen bonds, hydrophobic interactions, binding orientation, and interactions with key active-site residues.
5. Ignoring validation Before screening novel compounds, validate your docking protocol by re-docking the co-crystallized ligand. Without validation, your results may not be reliable.
Good docking isn't just about getting a score—it's about generating results you can confidently interpret and defend.
