In January 2014, the wwPDB launched a unified deposition, annotation, and validation system (RCSB PDB | PDBe | PDBj) for structures determined using X-ray crystallography. More than 14000 structures have been deposited, annotated, and validated using this system, with more than 9000 structures already released into the PDB archive. The new system uses the PDBx/mmCIF data format, which produces more uniform data, supports replacement of data files pre- and post-deposition, enhances communication with depositors, enables improved annotation, and provides validation reports based on recommendations from wwPDB expert task forces. Improvements to this system are regularly incorporated in response to user feedback. Detailed information and video tutorials are available.
An extended version of the unified wwPDB deposition, annotation, and validation system supporting structures determined by X-ray crystallography, NMR, and 3D EM was launched January 8th 2016. The extended system is integrated with the repositories for NMR and 3D EM experimental data and can assign both BMRB and EMDB accession codes.
Starting May 31st 2016, the legacy deposition systems, AutoDep, ADIT-NMR (BMRB|PDBj) and EMDep, will no longer accept new PDB and EMDB submissions. Depositors with in-progress sessions on the legacy systems will be able to access and complete their deposition sessions until September 30th 2016.
An updated ADIT-NMR system (available from BMRB and PDBj-BMRB) will continue to accept NMR data associated with a structure currently not accepted by the unified wwPDB deposition system (for example, relaxation data, and primary time-domain spectra) as well as experimental NMR data not associated with the deposition of 3D coordinates.
