X-RAY DIFFRACTION

Crystallization Details

Method	pH	Temprature	Details
X-RAY DIFFRACTION	7.5	298	Stock protein concentration: 6-9 mg/mL Well solution: 0.1 M HEPES-NaOH pH 7.5, 1.4-1.5 M ammonium sulfate, 10-20% (vol) glycerol Mix: 400 nL protein solution/seeds + 400 nL well solution Use of microseeding technique to improve crystal size. 1 microliter of a 100 mM Tbxo4 solution (ligand code 7MT) was added to the crystallization drop for a soacking of 1-2 minutes before freezing the crystals.
