ID	Method	pH	Temperature	Details
1	VAPOR DIFFUSION	4	294	CRYSTALLIZATION CONDITIONS: PROTEIN SOLUTION (12MG/ML, 20 MM K-PHOSPHATE BUFFER, PH 6.5) RESERVOIR SOLUTION (0.1 M CITRATE-PHOSPHATE BUFFER PH 4.0, 0.2 M AMMONIUM ACETATE, 25% PEG 4000). Before collecting the diffraction data, the crystal was soaked in reservoir solution containing 0.1 M NaF.
