Abstract

Cryo-electron microscopy reconstruction methods are uniquely able to reveal structures of many important macromolecules and macromolecular complexes. EMDataBank.org, a joint effort of the Protein Data Bank in Europe (PDBe), the Research Collaboratory for Structural Bioinformatics (RCSB) and the National Center for Macromolecular Imaging (NCMI), is a global 'one-stop shop' resource for deposition and retrieval of cryoEM maps, models and associated metadata. The resource unifies public access to the two major archives containing EM-based structural data: EM Data Bank (EMDB) and Protein Data Bank (PDB), and facilitates use of EM structural data of macromolecules and macromolecular complexes by the wider scientific community.

All images were created using OpenAstexViewer as implemented on the EMDB atlas pages for these entries.

Tools for 3D visualization of EM structural data. EM viewer (top left) and OpenAstexViewer (top right) are Java-based 3D viewers that can be launched from the EMDB atlas ‘Visualization’ pages. EM viewer employs a compact single contour-level mesh representation for lightweight map viewing; OpenAstexViewer enables exploration of maps and their fitted models with adjustable map contour level. The EMDataBank.org web service implemented in UCSF chimera (bottom panel) expedites search of the EMDB and subsequent map + model download. The example shown is GroEL [EMD-5001and PDB 3CAU; (73)].
