Crystals of Sa-iPGM. (a) The crystals obtained from 0.1 M HEPES pH 7.5, 20%(w/v) polyethylene glycol 10 000 (condition No. 38 from Crystal Screen 2, Hampton Research) using the sitting-drop vapour-diffusion method at 25°C measured 0.3 × 0.1 × 0.015 mm. (b) The crystals of Sa-iPGM grown from 0.2 M NaCl, 0.1 M bis-tris pH 6.5, 25%(w/v) polyethylene glycol 3350 (condition No. 71 from Index) by the sitting-drop vapour-diffusion method at 25°C measured 0.2 × 0.06 × 0.045 mm. |
