1VAPOR DIFFUSION, SITTING DROP293To obtain the inhibitor bound crystal form of TMK-S.aureus crystals were initially grown in the absence of compound using the sitting drop method at 293 K with a reservoir solution of 100 mM PCPT (propionate-cacodylate-bistris propane buffer) pH 7-8, 21-24% PEG 3350, 200 mM Mg2Cl using 1:1 protein:reservoir solution with the protein solution at 13 mg/mL. Crystals were harvested and soaked overnight in a solution containing 100 mM PCPT, 35% PEG 3350, 200 mM Mg2Cl and 1-2 mM or compound from a 100 mM DMSO stock. After soaking the crystals were cryoprotected by soaking for 15 minutes in compound-soak solution supplemented with 20% ethylene glycol., VAPOR DIFFUSION, SITTING DROP
