In order to meet the challenges of ever greater numbers of PDB depositions, involving ever larger and more complex structures, often determined using multiple methods, the Worldwide Protein Data Bank partners (wwPDB: http://wwpdb.org/) are developing a completely new system for deposition and annotation of PDB entries.

This new system will go into full production at all the wwPDB deposition sites early in 2014 and will then be able to handle depositions of structures of any size, determined using diffraction, NMR and/or EM methods. Large structures will also be processed and released intact so that "split entries" become a thing of the past.
