| Outline of Final Research Achievements |
In this study, we have developed a novel method that can perform a large-scale comparison of protein-ligand binding sites by utilizing a coarse-grained representation of binding sites and a fast sorting algorithm. Using the method, we conducted a large-scale all-pairs similarity search for both known and potential binding sites in the PDB, and constructed the database, called PoSSuM, that listed the discovered similar site pairs. PoSSuM has grown to provide information related to 49 million pairs of similar binding sites discovered among 5.5 million known and putative binding sites. For pharmaceutical applications, such as predictions of side effects and drug repositioning, we have provided a new database, PoSSuMds (PoSSuM drug search) to catalog detected known and potential binding sites for approved drug compounds whose assay data were retrieved from ChEMBL.
