Hi Xiaopeng,
There is no sign of extra density anywhere? Could the inhibitors be
binding at a site other than the active site? Is the active site
accessible from the solvent channels in the crystal?
If not, best thing I can suggest is to try and co-crystallise protein
with inhibitor - mix the two
Dear all,
We are working on protein-inhibitor complex crystal structures, although we
did get nice crystals and soaked them with inhibitor for several days, all
structures we obtained were empty!!There are nothing at the active site. For
several crystals. their color turned very clearly from
