Improved Deposition for Cryo-Electron Microscopy

PDB deposition systems have been extended to accept data items specifically describing cryo-electron microscopy (cryo-EM) methods, for those EM methods that generate fitted coordinates. These items were developed in collaboration with members of the cryo-EM community, the EBI-MSD group, and the PDB.

New versions of ADIT ( and and AutoDep ( that support these new data items for cryo-EM depositions are available.

Further information about AutoDep is available at

ADIT users can now select from the X-ray, NMR, or Cryo-EM deposition views. Further information about ADIT is available at

Cryo-EM data item definitions are available from the following sources:
