About EMDB

The Electron Microscopy Data Bank (EMDB) is a public repository for cryogenic-sample Electron Microscopy (cryoEM) volumes and representative tomograms of macromolecular complexes and subcellular structures. It covers a variety of techniques, including single-particle analysis, helical reconstruction, electron tomography, subtomogram averaging, and electron crystallography (for more information, see the EMDB Policies).

EMDB was founded at EMBL-EBI in 2002 under the leadership of Kim Henrick. From 2007, the archive has been operated jointly by EMBL-EBI and the Research Collaboratory for Structural Bioinformatics (RCSB)a. In 2013, the Protein Data Bank Japan (PDBj) also became involved in EMDB. As of the first of January, 2021, EMDB is an archive operated under the aegis of the Worldwide Protein Data Bank (wwPDB), and has also joined that organisation as a full member.

Results of cryo-EM studies are archived in three collaborating archives:

  • EMDB stores the processed 3D volumes and tomograms;
  • PDB stores any atomic models that have been constructed based on EMDB data;
  • EMPIAR stores the raw EM data underpinning the data in EMDB/PDB.

Data for EMDB and PDB can be deposited through the wwPDB deposition and annotation system OneDep.

EMPIAR (Electron Microscopy Public Image Archive) is a companion archive to EMDB, founded at and operated by EMBL-EBI, and with a mirror site at PDBj.
