by RCSB PDB / wwPDB Consortium · free · Last verified 2026-03-17
The RCSB Protein Data Bank (PDB) is the single worldwide archive of experimentally determined 3D structures of proteins, nucleic acids, and complex assemblies, currently containing over 220,000 biological macromolecular structures determined by X-ray crystallography, NMR, and cryo-EM. It is the foundational structural dataset for computational biology and was used to train and validate AlphaFold2 and other structure-prediction models.
