Crystallization

Crystalization Experiments
ID	Method	pH	Temperature	Details
1	VAPOR DIFFUSION, HANGING DROP	5.8	291	34 mg/ml enzyme incubated with 1.4 mM ThDP, 0.5 mM FAD, 14 mM MgCl2, 0.7 mM BSM and 4.5 mM DTT. Crystals were obtained my mixing equal volumes (300 nl) of well solution (1.6M Na/K hydrogen phosphate pH 6.5) and complex solution. Crystals were then soaked with pyruvate (added as powder in the drop) for 2 hours
