Protein Data Bank(PDB)

The Protein Data Bank (PDB) is a repository for the 3-D structural data of large biological molecules, such as proteins andnucleic acids. (See also crystallographic database). The data, typically obtained by X-ray crystallography or NMR spectroscopy and submitted by biologists and biochemists from around the world, can be accessed at no charge on the internet. The PDB is overseen by an organization called the Worldwide Protein Data Bank , wwPDB.
