Hi kooj1, Last week i did a very similar protein–ligand modeling job using existing PDB structures, and I’m confident to handle this really well. i would like to know the below. - Which target PDB IDs (and any cofactors/metal ions) should I use, and do you expect covalent binding or flexible side-chain handling? - What exact deliverables do you want: ranked hits with Vina scores, docked poses, MD stability plots, ΔG (MM/GBSA), and ADMET tables, in what formats? I think we should. - Use ensemble docking across multiple protein conformations to cut false negatives and improve hit quality. - Validate top hits with short MD then MM/GBSA, plus small QM (ORCA) on key contacts or metal centers for accuracy. Lets follow a plan like this. - I prep the protein(s): clean, add missing atoms, set pH/protonation, keep required cofactors, define binding pocket from known ligands. - I standardize ligands: tautomers/states, 3D minimization, remove PAINS, quick ADMET pre-filter to save compute. - I run HTVS in PyRx/AutoDock Vina (flex/covalent if needed), rescore and cluster, then shortlist the top 1–2%. - I validate: 25–100 ns MD for finalists, compute RMSD/RMSF and MM/GBSA ΔG; targeted ORCA QM on tricky sites; deliver poses, plots, methods, and clean Python notebooks so you can reproduce every step
