The compound helps to obtain crystals but is not visible in the structures. Add 0.5 mM ZnCl2. Add inhibitor, incubate for 16h on ice. Crystallize using microbatch setups with Al's oil (Hampton Research), with total drop size 1ul with 50% protein sample, using crystallization reagent of 0.1M Tris/HCl pH 8.5, 0.2M NaCl, 25% PEG 3350.
