DescriptionThe 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.PubChem is the world's largest open chemical database maintained by the NCBI, containing information on over 115 million compounds, 295 million substances, and 270 million bioactivity outcomes from more than 1.2 million assays. It provides standardized molecular structures, properties, and biological activity data freely accessible via REST API and bulk download, making it the canonical resource for cheminformatics and drug discovery research.
