X-RAY DIFFRACTION

Crystallization Details

Method	pH	Temprature	Details
X-RAY DIFFRACTION	5.1	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: 2% PEG 8K, 24 mM sodium acetate pH 5.1, 26 mM sodium acetate pH 5.5, 12.5 uM phosphotungstic acid
