From today, July 1st 2019, submission of PDBx/mmCIF format files for crystallographic depositions to the PDB is mandatory.

Refmac, Phenix.refine, and Buster programs can now output PDBx/mmCIF formatted files. For users of other structure determination/refinement software packages, the wwPDB provides stand-alone and web-based tools to convert legacy PDB format files into PDBx/mmCIF format: pdb_extract http://pdb-extract.wwpdb.org/ and MAXIT http://sw-tools.rcsb.org/apps/MAXIT/index.html . More information on outputting and preparing PDBx/mmCIF format files for deposition can be found on the wwPDB website https://www.wwpdb.org/deposition/preparing-pdbx-mmcif-files .
