Hi Katherine,
One possibility could be that you have occupancy of 0.5 and that ligand
binding at one site in the crystal distorts a second site so it cannot bind
ligand.
Occupancy refinement is not always very stable.
If you are looking at two structures on top of one another - refinement

Hello, the statistics all look good apart from the R-merge and R-meas. It might be worth looking at the processing again in case it can be improved. I assume you mean rms rather than A when you say the difference density only disappears at 6 A and, if so, it must be a strong feature. Does the fragm
Hi all,
I apologise in advance for the long post. I am working on solving a
structure that looks like it could have a ligand bound in the active site.
My data was obtained from a crystal of just the soluble domain of my
protein that had been soaked overnight in the ligand solution. The apo
