I have some ligand structures and I would like to which proteins it could interact to. For that I would like to use docking, and use all protein structures from PDB. Therefore I wonder whether a database or repository containing all 3D protein structures in docking ready format (pdb, mol2) exists.
The problem with structures in the PDB is that they contain ligands, solvent molecules, breaks in the polypeptide chain, and numerous numerous other problems that make docking programs crash unexpectedly. Curating a benchmark is a pain.. But anyway, I would indeed do this manually because it depends on what proteins your ligand is targetting (you should have an idea..)
