EM Data Bank

The EM Data Bank or EMDB is an extension of the Protein Data Bank (PDB) for 3D data collected from Cryo-Electron Microscopy data. This site is only site that provides the three-dimensional for non-viruses (which is filled by the Viper EMDB at Scripps).

While still in its early days, Cryo-Electron Microscopy is becoming an important tool in understanding biological molecules and all of these molecules are deposited in the EMDB. The PDB no longer accepts low-resolution structures.
