The Protein Data Bank (PDB) archive is the single worldwide repository of information about the 3D structures of large biological molecules, including proteins and nucleic acids.
These are the molecules of life that are found in all organisms including bacteria, yeast, plants, flies, other animals, and humans.
Understanding the shape of a molecule deduce a structure's role in human health and disease, and in drug development.
The structures in the archive range from tiny proteins and bits of DNA to complex molecular machines like the ribosome.
The PDB archive is available at no cost to users. The PDB archive is updated each week at the target time of Wednesday 00:00 UTC (Coordinated Universal Time).
The PDB was established in 1971 at Brookhaven National Laboratory under the leadership of Walter Hamilton and originally contained
7 structures. After Hamilton's untimely death, Tom Koetzle began to lead the PDB in 1973, and then Joel Sussman in 1994. In 1998,
the Research Collaboratory for Structural Bioinformatics (RCSB) became responsible for the management of the PDB. In 2003, the
wwPDB was formed to maintain a single PDB archive of macromolecular structural data
that is freely and publicly available to the global community. It consists of organizations that act as deposition, data processing
and distribution centers for PDB data.
In addition, the RCSB PDB supports a website where visitors can perform simple and complex queries on the data, analyze, and visualize the results. Details about the history, function, progress, and future
goals of the RCSB PDB can be found in our Annual Reports and
The PDB Advisory Notice defines the conditions for using data from the
PDB archive. Our Policies & References page describes copyright
RCSB PDB staff are located at Rutgers, The State University of New Jersey and the University of California, San Diego.
Job listings for open positions are posted online.
The Rutgers group has been featured on RU-tv
and Biophysical Society TV.
The RCSB PDB has an international community of users, including biologists (in fields such as structural biology, biochemistry,
genetics, pharmacology); other scientists (in fields such as bioinformatics, software developers for data analysis and
visualization); students and educators (all levels); media writers, illustrators, textbook authors; and the general public.
The website (rcsb.org) is accessed by about 286,000 unique visitors per month from about 190 countries. Around 1.3 Terabytes of data are transferred each month from the website.
The RCSB PDB Advisory Committee is made up of an international team of
experts in X-ray crystallography, cryoEM, NMR, bioinformatics and education. RCSB PDB appreciates the valuable feedback they provide on
an ongoing basis.
The RCSB PDB is a member of the
wwPDB, a collaborative effort with
PDBj (Japan), and
BMRB (USA) to ensure the PDB archive is global and uniform.
As the wwPDB archive keeper, the RCSB PDB updates the PDB archive at ftp://ftp.wwpdb.org weekly. The structures included in each release are
highlighted on the RCSB PDB home page and clearly defined on the FTP site. These sites are maintained 24 hours a day, seven days a week. A
failover system automatically redirects internet traffic to a mirror site, if needed.
