http://www.rcsb.org/pdb/The Protein Data Bank (PDB) is the single worldwide archive of structural data for biological macromolecules. The PDB is maintained by the Research Collaboratory for Structural Bioinformatics (RCSB). The Protein Data Bank (PDB) is the single international repository for public data on the 3-dimensional structures of biological macromolecules. The contents are primarily experimental data derived from X-ray crystallography and NMR experiments. The primary goals of this resource are:
To enable you to locate structures of interest; To perform simple analyses on one or more structures; To act as a portal to additional information available on the InternetTo enable you to download information on a structure, notably the Cartesian atomic coordinates, for further analysis. The PDB database is available for complete download via ftp from ftp://ftp.rcsb.org/pub/pdb/data/structures/all/pdb/, and incremental updates are made possible using the rsync protocol (SERVER = rsync.rcsb.org, PORT = 33444).
