Crystallization Crystalization Experiments ID Method pH Temperature Details 1 VAPOR DIFFUSION, HANGING DROP 7.5 295 1 uL of 10 mg/mL UL44 in the storage buffer (20 mM Tris (pH 7.5), 500
mM NaCl, 0.1 mM EDTA, 2 mM DTT and 5% glycerol) and 1 uL crystallization buffer (75 mM ammonium sulfate, 50 mM HEPES (pH 7.5) and 10% PEG4K) were mixed in hanging drops. Crystals were obtained by vapor diffusion over a 1.8 M NaCl
solution, after one day
