1	VAPOR DIFFUSION, SITTING DROP	6.5	277	Crystals were grown by mixing 1uL of the protein/DNA complex with 1uL of mother liquor (85mM MES pH 6.5, 85mMCaCl2, 42.5mM NaCl, 8.5% PEG3350, 11% glycerol), using the sitting drop vapor diffusion technique. Crystals were transferred to a cryoprotectant solution containing 0.1M MES pH 6.5, 0.1M CaCl2, 50mM NaCl, 10mM MgCl2, 20% PEG3350, 15% glycerol in three steps. , VAPOR DIFFUSION, SITTING DROP, temperature 277K
