Neat! It's true the PDB will choose a unique code for you,
but they will use what you supply if it is already unique,
and it is nice to be able to choose something that can help
you remember what it stands for.
Gone are the days when we could choose meaningfull pdb ID's
(like 1PRC, 2PRC, 3PRC etc are all photosynthetic reaction center),
but there is still some freedom in choosing the ligand ID's.
They are filling up fast, though!
locust 123% elbow.get_new_ligand_code AC
Unique ligand code : AC3
locust 129% elbow.get_new_ligand_code "A?3"
Unique ligand code : A?3

Hi Eleanor
I use any 3 letter/number code that i want. If you read the
corresponding cif file into coot it is used in preference to any in the
library. The PDB deposition team will assign a code if it is a new ligand to
the database. Could you relay this to original poster?

I use your method - trial & error..
It would be nice if at least there was a list somewhere of
unassigned codes!

Hi,
What is the proper way of generating 3-letter code for a new
ligand? As of now, I insert my ligand in Coot using smiles string and for the
3-letter code I picked a non-existent code by trial and error (not very
efficient). A cif file with corresponding name which I generated using Phenix
was imported into Coot.
I am sure there is a proper way of doing this. Appreciate your
feedback.

Sze Yi
