How to fill out refinement of alphafold-multimer structures

How to fill out refinement of alphafold-multimer structures

1. Obtain the initial predicted structure from AlphaFold-Multimer.
2. Load the structure into a molecular visualization tool (e.g., PyMOL, Chimera).
3. Analyze the structure for any potential issues (e.g., steric clashes, incorrect bonding).
4. Prepare the structure for refinement by adding missing atoms or residues if necessary.
5. Select an appropriate refinement method (e.g., molecular dynamics simulations or energy minimization).
6. Set the parameters for the chosen refinement method, including temperature and time steps.
7. Run the refinement simulation and monitor convergence.
8. After completion, analyze the refined structure for any improvements compared to the initial structure.
9. Validate the final refined structure using tools like MolProbity or ProQ.
10. Save the refined structure in the desired file format for further analysis or visualization.
