The Protein Data Bank (PDB) is a global repository for 3D structural data of biological macromolecules. Key features:
Contains atomic coordinates and metadata for proteins, nucleic acids, and complex assemblies Archives experimentally determined structures from X-ray crystallography, NMR, cryo-EM Provides standardized format (PDB format) for structural data Offers visualization tools and structure analysis resources Includes detailed metadata about experimental methods, quality metrics Used worldwide by researchers in structural biology, drug design, and bioinformatics
Maintained by the Worldwide Protein Data Bank organization (wwPDB), it serves as the primary database for biomolecular structure data.
