Crystallization Details
Method pH Temprature Details
X-RAY DIFFRACTION 5.5 303 Protein was mixed with the annealed oligonucleotide using a stoichiometric ratio of 1.25:1 DNA to protein in 1X DNA binding buffer. Reactions were incubated for thirty minutes at 65 C. Crystals started to appear within minutes of setting up the trays in 1:1 or 2:1 well to complex ratio. Well solution: 10% PEG 600, 50 mM sodium succinate pH 5.5, 200 mM potassium chloride, 10 mM magnesium chloride, 1 mM spermine
