Deposition Statistics
In the first quarter of 2025, 5283 experimentally-determined structures were deposited to the PDB archive for a total of 5283 entries deposited in the year. Data are processed by wwPDB partners RCSB PDB, PDBe, PDBj and PDBc.
Of the structures deposited in 2025 so far, 80.2% were deposited with a release status of hold until publication 13.7% were released as soon as annotation of the entry was complete and 6.0% were held until a particular date. 58.1% of these entries were determined by X-ray crystallographic methods 1.2% were determined by NMR methods and 40.4% by 3DEM.
During the same time quarter, 4244 structures were released in the PDB, including 175 SARS-CoV-2 structures. 2855 EMDB maps were released in the archive.
Structures from Integrative Hybrid Methods
Integrative structures are available at wwPDB.org and the PDB archive
PDB-Dev now PDB-IHM
The PDB-IHM (formerly PDB-Dev) ecosystem provides a robust infrastructure for depositing, curating, validating, visualizing, archiving, and disseminating integrative structures of biomolecules and their complexes.
Structures of many large macromolecular assemblies are now being determined using integrative approaches, wherein information derived from multiple experimental and computational methods is combined to compute their three-dimensional structures. PDB-IHM is a system for archiving and disseminating structures determined using integrative or hybrid methods (IHM), and making them Findable, Accessible, Interoperable, and Reusable (FAIR).
Integrative structures can be deposited through the PDB-IHM deposition portal and accessible from the wwPDB OneDep home page. They are processed in parallel to the wwPDB OneDep system, and assigned PDB accession codes and Digital Object Identifiers (DOIs). Structures processed by PDB-IHM are released synchronously into the PDB archive as part of the weekly PDB update.
IHM Validation Reports
Updated validation reports (version 2) are now available in the PDB archive and on the PDB-IHM website. The latest update extends IHM validation to structures derived from Chemical Crosslinking Mass Spectrometry (Crosslinking-MS) data, in addition to the previously supported Small Angle Scattering (SAS) data. This milestone is the result of close collaboration among the Crosslinking-MS community, PRIDE repository, and the PDB-IHM team.
