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 XIV 6.3MG/ML IN 10MM TRIS-HCL PH 7.4, 25MM NACL, WITH A 7-FOLD EXCESS OF BMC020 ADDED FROM A 50MM STOCK SOLUTION IN 90% DMSO, 10% H2O. CRYO-PROTECTANT WAS 1.2M AMMONIUM PHOSPHATE, 0.1M SODIUM CITRATE, 25%(V/V)GLYCEROL, 2.0% DMSO, 1MM BMC020.
