1	VAPOR DIFFUSION, SITTING DROP	7.5	295	Crystals were grown by mixing 1uL 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 transferred in two steps to a cryoprotectant solution containing 0.1M HEPES pH 7.5, 10mM MgCl2, 50mM NaCl, 20% PEG4000, 5% glycerol, 15% ethylene glycol, 10mM dTTP for 16 hours. The crystals were then backsoaked in cryoprotectant containing 2mM pyrophosphate. , VAPOR DIFFUSION, SITTING DROP, temperature 295K
