ID	Method	pH	Temperature	Details
1	VAPOR DIFFUSION, SITTING DROP	6.1	293.15	Crystals were grown by vapor diffusion, sitting drop method. Drop volume was 2 micro-liter (1+1) equilibrated against 50 micro-liter of reservoir volume of 1.7 M malic acid at pH 6.1. The concentration of protein was 30 mg/ml in HEPES buffer at pH 7.5 containing 150 mM of NaCl
