ID	Method	pH	Temperature	Details
1	VAPOR DIFFUSION, HANGING DROP	3.9	277	2 micro L of Selenomethionine containing GGCT (15mg/ml in 20 mM Tris/HCL 0,1mM dithiothreitol pH8.0) was mixed with equal volumes of gamma-glu-glu dipeptide (40mM) and well solution. The well contained 1ml of a solution comprising PEG 4000 (22.5% w/v), 100mM sodium formate buffer pH3.9, 200mM ammonium acetate. , VAPOR DIFFUSION, HANGING DROP, temperature 277K
