PDBsum   Pictorial database of 3D structures in the Protein Data Bank

PDBsum is a pictorial database that provides an at-a-glance overview of the contents of each 3D structure deposited in the Protein Data Bank (PDB). It shows the molecule(s) that make up the structure (ie protein chains, DNA, ligands and metal ions) and schematic diagrams of the interactions between them.         Read more ...


PDB code  (4 chars)    Example: "1kfv"

Text search 
Scans all TITLE, HEADER, COMPND, SOURCE and AUTHOR records in the PDB (eg to find a given protein by name).

Search by sequence

Perform FASTA search vs all sequences in the PDB to get a list of the closest matches.

Search by  
UniProt id:
(eg P03023, LACI_ECOLI, etc)
Pfam id:
(eg PF07992)
Ensembl id:
(eg ENSG00000086205, ENST00000256999)


* Enlarged versions of the Pfam domain diagrams on each entry's page can now be obtained via the + icon.
* A search for PDB structures by Ensembl gene/transcript identifier (ENSG/ENST) has been added to UniProt and Pfam searches above.
* Human variation data from the 1,000 Genomes Project is now included on the 'protein' pages of human proteins, showing where in the protein the natural variations occur (eg 3bfx).
* You can use the Generate option on the left to submit your own structure and get a password protected PDBsum analysis generated for it.

PDBsum in-house

PDBsumProprietary: For companies wishing to have PDBsum processing and display in-house for their proprietary structures (from x-ray crystallography, NMR spectroscopy, homology modelling or docking predictions) there is the opportunity to license the PDBsum pipeline software. For more details, please contact Dr Mark Swindells of EBISU at



The development of PDBsum has been partly funded by the Wellcome Trust spacer
