1	VAPOR DIFFUSION, SITTING DROP	6.5	289.15	20uL 25.0 mg/mL FphE (10mM HEPES pH 7.5, 100mM NaCl) were mixed with 3uL Z27 (50mM in DMSO) and incubated at 4C overnight. 0.3 uL FphE-Z27 solution was mixed with 0.15 uL of reservoir solution. Sitting drop reservoir contained 25 uL of 180mM Calcium acetate, 100mM MES pH 6.5, 22.5% PEG 2000 MME. Crystal appeared within 2.5 days at 16C and grew until 14.5 days when it was frozen in a solution of ~25% glycerol, 75% reservoir.
