ID	Method	pH	Temperature	Details
1	VAPOR DIFFUSION, SITTING DROP	6.5	293	Crystals were grown in a MRC SD2 microplate, set with a TTP Labtech Mosquito crystallization robot. In the crystallization experiment leading to the crystal used for data collection, 200 nL of protein solution at 10.5 mg/mL was combined with 250 nL reservoir solution, composed of 20% PEG3350, 0.2M CaCl2, 0.1M bistris buffer pH 6.5. Crystals were cryopreserved by soaking in reservoir solution supplemented to 30% PEG3350 and immersion in liquid nitrogen
