Hi All,
For a tutorial, we would like to demonstrate the method of ligand
soaking in protein crystals. I am thinking about using some sort of
native ligand or inhibitor that can be easily identified in the electron
density rather than halide or heavy atom derivatization.
Does anybody have

Dear Uli,
the geometric ligands (I3C, B3C, B4C) by Tobias Beck
(http://www.protein.ethz.ch/people/tobias/) are both commercially
available and easily identified. I3C is suitable for inhouse data
collection and provide a strong anomalous signal.
Of
Human carbonic anhydrase II and any sulfonamide. We use a variety of
alkylsulfonamides (everyone can have a different ligand and they are
easy to model) or you can use commercially available inhibitors like
benzenesulfonamide, sulfanilamide, acetazolamide, etc. A 30 second soak
is sufficient

Perhaps lysozyme complexed with some sugar?
