1	hanging drop	5	292	CRYSTALS WERE GROWN AT 19C BY VAPOUR DIFFUSION IN HANGING DROPS, FROM 1.0M AMMONIUM PHOSPHATE, 0.1M SODIUM CITRATE, PH 5.0. PROTEIN STOCK WAS BACE MUT46B BATCH XVI 7.0MG/ML IN 10MM TRIS-HCL PH 7.4, 25MM NACL, WITH A 6-FOLD EXCESS OF BMC015 ADDED FROM A 50MM STOCK SOLUTION IN 90% DMSO-D6 (1.7% DMSO IN DROP). A SOLUTION CONTAINING 1.2M AMMONIUM PHOSPHATE, 0.1M SODIUM CITRATE PH 5.0, 25% GLYCEROL, 1MM BMC015 AND 1.8% DMSO WAS USED AS CRYO-PROTECTANT.
