One thing to beware of is that of course un-released structures may have
the code that you choose - structures can be on hold for over a year (the
rules say a year but in practice release is often slower) and any new
ligands and codes with them. Ligand codes are assigned at deposition and
the descr
Hi Colin,
You can define an UNL (unknown ligand) in the blob. This is the standard name
for such a
compound. It becomes a bit messy in refinement in terms of restraints, but it
does exactly
what you want it to do: say you noticed the blob but couldn't figure out what

Dear Colin,
I believe people usually refer to it as "unidentified blob" when

better options.

Dear all,
I am currently working on a structure that contains a residual density feature
located within the active site. Due to a combination of factors including
limited occupancy, modest resolution, twinning etc it has not been possible to
unambiguously identify this feature despite fairly ex
