All crystallization were performed in anoxic chamber (N2/H2, 95:5 %) with anaerobic solutions. Crystals were obtained by initial screening at 291.15 K using the sitting drop method on a 96-well MRC 2 Crystallization Plates in polystyrene (SWISSCI). The crystallization reservoir contained 90 uL of mother liquor, crystallization drop contained a mixture of 0.6 uL protein and 0.6 uL precipitant.
The best diffracting crystal of CaCODH/ACS from heterotrophic growth on fructose was obtained by initial screening using the Wizard 3 & 4 screen from Jena Bioscience. The crystallization reservoir contained 100 mM BIS-TRIS propane, pH 6.5; 200 mM Sodium fluoride and 20% (w/v) Polyethylene glycol 3,350. The initial protein concentration was 16.4 mg/mL. |
