Message from RCSB PDB

The PDB was announced on October 20, 1971 in Crystallography: Protein Data Bank Nature New Biology 233: 223 (1971) doi: 10.1038/newbio233223b0.

Fifty years later, the PDB archive contains ~180,000 structures of proteins, nucleic acids, and complex assemblies that helps students and researchers understand all aspects of biomedicine and agriculture, from protein synthesis to health and disease. It is managed by the Worldwide PDB (wwPDB) organization that ensures that the PDB is freely and publicly available to the global community.

Throughout 2021, the wwPDB is celebrating the 50th anniversary of the PDB archive. Visit for information about upcoming events, including:

The 2021 ACA Transactions Symposium (July 30-31, 2021) was dedicated to celebrating the PDB50; a meeting report is included in this newsletter.
