I’m afraid I can’t give you any details how to do it, but `pdb2gmx` is not a suitable tool. See [Fatal Error: Residue Not Found in the Residue Topology Database](https://gromacs.bioexcel.eu/t/fatal-error-residue-not-found-in-the-residue-topology-database/6215) for a starting point, but unfortunately not a complete protocol.
