ID	Method	pH	Temperature	Details
1	VAPOR DIFFUSION, SITTING DROP	5.5	298	Crystallized by sitting drop vapor diffusion with 0.6 ml reservoirs and drop volumes 6 ul. Drops consisted of equal volumes of the reservoir and the protein stock solution. The reservoirs were 20% w/v PEG 3350 with 0.1 M HEPES buffer. The protein was in the growth broth of the aspergillum expression system and was not further purified. The stock protein concentration was 30 mg/ml
