File Format Description

Data file created in the Protein Data Bank (PDB) format; stores 3D coordinates specifying the structure of atoms within a protein or other chemical compound; used as a standard format for studying protein structures; also used by the Research Collaboratory for Structural Bioinformatics (RCSB) for studying biological macromolecules.

Many Protein Data Bank files are made available through the Worldwide Protein Data Bank (wwPDB), an organization that archives macromolecules and freely distributes them.

NOTE: PDB files are often viewed within a Java applet that uses Jmol, an open source molecule visualization package. PDB files are also supported by some molecular viewing browser plugins.
