Protein Data Bank (PDB) format data file with three-dimensional coordinates which define the structure of atoms within a protein or other chemical compound. It serves as a default format to study protein structures and is also used by the Research Collaboratory for Structural Bioinformatics (RCSB) to study biological macromolecules. The Worldwide Protein Data Bank provides many PDB files for free distributing. These files are usually opened using a Java applet which uses Jmol (open source molecule visualization archive). Several molecular viewing browser plug-ins are also compatible with PDB files.
