Dear Authur As the PDB format is not suitable for structures with over 99,999 atom lines or over 62 chains we only distribute these structures in both mmCIF and PDBML formats.
See: http://www.wwpdb.org/news/news?year=2014#10-December-2014 We (PDBe) have been using mmCIF format in pymol for number of years to generate our images.
