Hi all,

In 2002 I asked the BB a question to which I received many useful responses, 
showing the power of crowd-sourcing (although that term didn't exist yet at 
the time I think) - http://www.ysbl.york.ac.uk/ccp4bb/2002/msg00887.html

Now I would like to pick the collective CCP4 Bulletin Brain again:

Does any of you know of any examples (available in the PDB) where the same 
ligand is observed in two distinctly different conformations (with convincing 
support in the density) in one and the same structure (i.e., same PDB entry)? 
This could for example be two copies of a ligand bound to a dimer in different 
poses. I'm interested only in distinct sites, not multiple conformations in 
one site.

I will happily summarise the replies.

Best wishes,

--Gerard
