To assay for oxidoreductase activity, the purified recombinant proteins were incubated in 100-μl reactions at 37 °C overnight with 1 mg/ml 2,7-anhydro-Neu5Ac or Neu5Ac in 20 mm sodium phosphate buffer, pH 7.5, in the presence 500 μm NADH. The structure was acquired from a crystal grown in the JCSG Plus screen (100 mm sodium citrate, pH 5.5, 20% PEG 3000). The diffraction experiment was performed on the I04 beamline at Diamond Light Source Ltd.
