Dear CCP4ers,

I'm desperately trying to dig out a good documentation of the new PDB 3.2 nomenclature on www.wwpdb.org, but find myself running in circles. There is even a broken link to the nomenclature file http://remediation.wwpdb.org/downloads/Components-rel-alt.cif. The other link, ftp://ftp.wwpdb.org/pub/pdb/data/monomers, is a cryptic collection of compounds. Why isn't there a document for PDB 3.2 that covers the main dictionaries for amino acids, nucleic acids, sugars, water and so on (maybe with a useful link to more exotic compounds) like for the old PDB 2.3? Currently, I have to rely on the "remediator" program from the Richardson lab for that, without even knowing whether it is always correct. How could I possibly write a program that reads/writes PDB 3.2 files correctly?

I would be very grateful for any useful document.

Best regards,

Dirk.
