Effective February 1, 2008, structure factor amplitudes/intensities (for crystal structures) and restraints (for NMR structures) will be a mandatory requirement for PDB deposition.

These data must be deposited at a member site of the Worldwide Protein Data Bank ( www.wwpdb.org ): PDBj ( www.pdbj.org ), RCSB PDB ( www.pdb.org ), PDBe ( www.ebi.ac.uk/msd ), or BMRB ( www.bmrb.wisc.edu ).

Data can be released as soon as they have been processed and approved. There is a one-year limit on the length of time a structure and its experimental data can be put on hold, including structures that are on hold until the associated paper is published (HPUB).

This policy was developed as a result of comments and recommendations from the PDB user community, including the Commission on Biological Macromolecules of the International Union of Crystallography and the NMR Task Force, and has been endorsed by the wwPDB Advisory Committee.
