Improved Access to Chemical Component Definitions

02/22

Individual Chemical Component entries are available for download from the PDB Archive as individual files

Individual Chemical Component Dictionary (CCD) and Biologically Interest molecule Reference Dictionary (BIRD) definitions are now accessible in an FTP tree in the PDB archive. In response to user requests, these individual CCD and BIRD entry files can be found at /pdb/refdata/chem_comp/ and /pdb/refdata/bird/, respectively with last character hash as sub-directory.

For example:

• /pdb/refdata/chem_comp/C/D8C/D8C.cif
• /pdb/refdata/bird/prd/8/PRD_001068.cif
