Body: <p>The <a href="https://www.rcsb.org/pdb/ligand/drugMapping.do" rel="nofollow noreferrer">drug and drug target mapping</a> tool shows the <strong>top 3</strong> PDB IDs for each drug based on the drug target sequence similarity search and ligand id search. Is there a way to get all the PDB ids of the drug-target PDB files and not only the top 3?</p>
  
  <p>I know you can get this information after clicking the "find" button under the last column of the output table (the column named "All PDB"), but I have a query of several hundreds of drugs and I'm not willing to do it manually for each result.</p>

  The [drug and drug target mapping](https://www.rcsb.org/pdb/ligand/drugMapping.do) tool shows the **top 3** PDB IDs for each drug based on the drug target sequence similarity search and ligand id search. Is there a way to get all the PDB ids of the drug-target PDB files and not only the top 3?
