Sun., June 21st 2015 Good evening, adding several general points to the thread. (1) Fundamentally PDB unlike other chemical databases insists that all equal structures should have the same 3-letter code and the same atom names - obviously for amino acids and say ATP. (1.1) Needless to say t

Miri raises important points about issues in the PDB Chemical Component Dictionary - I think part of the problem is that this is published completely separately from the actual PDB - so for example I don't think we have an archive of the CCD for comparison alongside the PDB snapshots? This makes it

I can't imagine a journal doing that can you? When I work on my supplementary material in a paper I don't expect that the journal will take a bit out and publish it separately to support the work of my competitors. Not out of spite that I was beaten - but because I don't want to take the respon

Well the problem is there is a lot more to a ligand than PDB coordinates - little things like bond orders... In addition people can publish ligands with atoms for which they have no density - so zero-occupancy is allowed too. So who should get priority - the group who publishes a ligand first, or t
