1	VAPOR DIFFUSION, HANGING DROP	5	298	Inhibitor GRL-02031 was dissolved in dimethylsulfoxide (DMSO). Crystals were grown using 1:5 molar ratio of protease (at 3.9 mg/ml) to inhibitor. The reservoir contained 0.1 M citrate phosphate buffer, pH 5.0, 0.35 M NaCl and 4% DMSO. Crystals were mounted on a nylon loop and flash-frozen in liquid nitrogen with a cryoprotectant of 30% v/v glycerol, VAPOR DIFFUSION, HANGING DROP, temperature 298K
