September 2013: 3DEM Deposition Rate, Journal Policies
The use of 3D cryo-electron microscopy reconstruction (3DEM) methods to experimentally determine structures of biological macromolecules, complexes and machines is rapidly increasing in the structural biology community. For journal articles reporting new 3DEM structures via single particle, helical, electron crystallography, and sub-tomogram averaging methods, we find that the overall map-deposition rate to EM Data Bank (EMDB) is approaching 70%. However, the rate varies significantly per journal, and tends to be highest for journals with well-defined and consistently enforced 3DEM deposition policies in place.
