X-RAY DIFFRACTION ? 293 N6 crystals were grown by hanging-drop vapour diffusion against 1:1 20%(w/v) PEG-3350 and 2 microM CaCl2 in 150mM NaCl at 20 degrees celsius, starting with equal volumes of N6 (20mg/ml in saline) and 20% (w/v) PEG 3350 and 2 microM in 1% saline. Microseeding with crystals of native N6 was carried out using a super saturated solution of N6 NA in 20% PEG 3350. Inhibitor complex obtained by soaking N6 crystals in a solution of 20% PEG 3350 in 1% saline (mother liquor) containing 27mM DANA at pH7 for 3 hours at 18 degrees celsius.
