KARI was crystallized at 13.5 mg/ml in the following buffer 25 mM Tris/HCl pH 7.6, 2 mM dithiothreitol, 10% glycerol. The reservoir was filled with 90 ul crystallization solution (33 % (w/v) PEG 5000 MME, 100 mM MES/NaOH pH 6.5 and 200 mM ammonium sulphate). Drops of 0.7 ul protein with 0.7 ul of crystallisation solution were applied on the shelf.
Crystals were firstly soaked in the crystallisation solution supplemented with 20 mM NADP, 50 mM L-Tartrate and 50 mM MgCl2 for 3 minutes, and then soaked in the crystallisation solution supplemented with 30 % v/v glycerol before freezing. |
