Protein Structure Servers
The Primary Database
  1. The World Wide Protein Data Bank (www.wwpdb.org): access to all published, empirical macromolecular 3D structure data.
Examples of Derived Databases
  1. Proteopedia.Org: All PDB entries in Jmol. Ligands and sites. A wiki with scene-authoring tools.
  2. Probable Quaternary Structure: Specific oligomer prediction and coordinates.
  3. Discovering similar structures without reference to sequences (VAST, FSSP/Dali).
  4. Model quality by atomic contact analysis after adding all hydrogen atoms (MolProbity).
  5. Finding conserved patches on protein surfaces (ConSurf).
  6. Structure prediction by comparative modeling from sequence alignments, or threading-based models (Structure Prediction Meta-Server).
