Protein Data Bank
The Protein Data Bank (PDB), operated by the Research Collaboratory for Structural Bioinformatics (RCSB), is an international repository for the processing and distribution of 3-D macromolecular structure data primarily determined experimentally by X-ray crystallography and NMR. Retrieve structure files, search for proteins with the PDB ID or with keywords, contribute new structure data, find entries awaiting release, and more.
