An equimolar ratio of delta79AAG and 13-mer single-stranded (ss) EDC DNA were mixed to form a protein-DNA complex concentration of 0.3 mM in the complex buffer (20 mM HEPES-NaOH, pH 7.5, 100 mM NaCl, 0.1 mM EDTA, 5% v/v glycerol and 1 mM DTT). The complex was incubated on ice for 15 min and used for crystallization. Crystals were obtained upon mixing 1 uL of protein-DNA complex and 1 uL of reservoir solution (100 mM BIS-TRIS, pH 5.5, 200 mM cesium chloride and 20% polyethylene glycol (PEG) 3350) over 0.5 ml of reservoir solution. Crystals appeared after incubation for 14 days at 22 degrees C, VAPOR DIFFUSION, HANGING DROP, temperature 298K |
