Crystalization Experiments
ID	Method	pH	Temperature	Details
1	VAPOR DIFFUSION, SITTING DROP	7.5	295	Crystals were grown by mixing 1uL of protein/DNA mixture with 1uL mother liquor (85-90mM HEPES pH 7.5, 17-18% PEG4000), using the sitting drop vapor diffusion technique. Crystals were then transferred to a cryoprotectant solution containing 0.1M HEPES pH 7.5, 10mM MgCl2, 50mM NaCl, 20% PEG4000, 5% glycerol, 1mM dUMPNPP in two steps. , VAPOR DIFFUSION, SITTING DROP, temperature 295K
