Crystallization

Crystalization Experiments
ID	Method	pH	Temperature	Details
1	VAPOR DIFFUSION, HANGING DROP	6	298	12-15% (v/v) polyethylene glycol 3350, 0.02 M MES and 10 mM manganese chloride. Crystals were dehydrated overnight in reservoir solution with increased (35%) (v/v) polyethylene glycol 3350 before cryo-stabilisation in 38% (v/v) polyethylene glycol 3350, 0.088 M MES (pH 6.0) and 44 mM manganese chloride for 6-8 h prior to data collection. MilliQ water was added to the stabilisation solution, VAPOR DIFFUSION, HANGING DROP, temperature 298K
