Drug ReposER facilitates the searching and comparisons of amino acid side chain arrangements that are similar to those found in drug binding sites and can be used a starting point to identify and explore potential targets for drug repurposing.

Three search options are provided:
1. Searching existing PDB structures for amino acid 3D patterns similar to known drug binding interfaces
2. Searching for binding interfaces of a drug molecule
3. Searching a user provided PDB structure for amino acid 3D patterns similar to known drug binding interfaces

Each entry and search results can be visualized using the integrated NGL viewer. Scripts for molecular docking in UCSF Chimera for search results can also be downloaded.


Search for amino acid arrangements similar to known drug binding sites in known target structures / protein-drug complexes

Determine whether the query PDB ID or PDB bound to query ligand ID contains similar patterns of amino acids to binding interfaces for known drug molecules (potential role in repurposing strategies)
