After deposition (my experience is with RCSB) you will get back a processed
file to verify.  See how the waters have been renumbered, and renumber
in such a a way that your original scheme is easily identifiable but in
keeping with whatever the renumbering was trying to achieve- e.g. your
waters X1,X2,X3 could become A1001, A1002, A1003 and the symmetry related
waters B1001, B1002, B1003. Discuss with the annotator to see how your
waters can be renumbered in a recognizable way in keeping with requirements
of the PDB conventions. Then in future depositions keep this same scheme
(you may still need to renumber the original processed file each time).

Hi all,
during deposition of structures the water numbering is frequently changed.
I would love to keep specific numbers for critical water molecules e.g.
in an active site in related proteins (mutants, ligand soaks), to
facilitate easier discussion in a manuscript.

Is there a general agreement how to treat these?

One way to deal with this is would be to use an arbitrary offset:
A1-A233 protein
A301 ligand
A302 another ligand
A401-404 4 special waters
A500- general solvent

Any input welcome ;-)
All the best,
Eckhard
