PDBsum is a database that provides an overview of the contents of each 3D macromolecular structure deposited in the Protein Data Bank (PDB).

[1][2][3][4] The original version of the database was developed around 1995 by Roman Laskowski and collaborators at University College London.

[5] As of 2014, PDBsum is maintained by Laskowski and collaborators in the laboratory of Janet Thornton at the European Bioinformatics Institute (EBI).

[6] The RasMol and Jmol molecular graphics software are used to provide a 3D view of molecules and their interactions within PDBsum.

One branch of PDBsum, known as DrugPort, focuses on these models and is linked with the DrugBank drug target database.
