1	VAPOR DIFFUSION, SITTING DROP	5.5	291	MtAPSK (0.7 ul) with 2 mM MgCl2 at a protein concentration of 17.6 mg.ml-1 was mixed with 0.7 ul reservoir solution. Crystals were obtained in the following crystallization condition: 20 % w/v polyethylene glycol 3350 and 100 mM tri-Sodium citrate pH 5.5. The cryoprotectant used for the crystals was 20 % w/v polyethylene glycol 3350, 100 mM tri-Sodium citrate pH 5.5 and 25% v/v ethylene glycol.
