1hanging drop292CRYSTALS WERE GROWN AT 19C BY VAPOUR DIFFUSION IN HANGING DROPS USING 1.0M UNBUFFERED AMMONIUM SULFATE AS PRECIPITANT. PROTEIN STOCK WAS BACE MUT46B BATCH X 8.3MG/ML IN 10MM TRIS-HCL PH 7.4, 25MM NACL, WITH A 4-FOLD EXCESS OF BMC022 ADDED FROM A 50MM STOCK SOLUTION IN DMSO (1.4% DMSO IN DROP). CRYO-PROTECTANT WAS 2.0M LI2SO4, 0.2M SUCROSE, 0.1M CITRATE PH 5.5.
