RCSB PDB: Homepage

On July 21, 2027, wwPDB will fully transition to extended 12-character PDB IDs, the PDBx/mmCIF format, and the re-organized PDB archive.
Start using the PDB Beta Archive today.

RCSB Protein Data Bank (RCSB PDB) enables breakthroughs in science and education by providing access and tools for exploration, visualization, and analysis of:

	Experimentally-determined 3D structures from the Protein Data Bank (PDB) archive
	Integrative 3D Structures from the PDB Archive
	Computed Structure Models (CSM) from AlphaFold DB and ModelArchive

Learn to effectively use tools for deposition, searching, analysis, and visualization of PDB data

Features & Highlights

Remediation of Metal-containing PDB Entries and CCDs

Improved accuracy and annotation metal-containing PDB Entries and CCDs are now available in remediated PDB data.

Paper Published about the PDB Beta Archive

Read about changes that will become the default on July 21, 2027. Transition to this new architecture today.

Use Shortlinks to Transition to the PDB Beta Archive

The PDB Beta Archive will replace the current archive July 21, 2027. Shortlinks are available now to help programmatic users with this transition.

New tools support deposition of structures to the wwPDB PDB and 3DEM Core Archives directly from structure determination software packages

Upload structures to the wwPDB OneDep system directly from refinement software packages

Reuse Metadata from Previous PDB Depositions

The refactored “Based on previous” workflow allows depositors to selectively import and reuse mmCIF metadata from a previously deposited PDB entry with method-aware safeguards, macromolecule checks, ORCID search, and transparent import logging.

Big PDB Changes Are One Year Away: Extended PDB IDs, the PDB Beta Archive, and PDBx/mmCIF

On July 21, 2027, the wwPDB will fully transition to extended PDB IDs for new depositions and the PDB archive will use a new directory structure based on 12-character extended PDB IDs. Users should adopt these upcoming changes today.

Improved OneDep Support for 3D ED/MicroED

3D ED/MicroED Electron Crystallography metadata are now collected and represented using a macromolecular crystallography data model co-developed by the community.
