実験手順

The assay mixture contained 2 g (wet weight) of Bacillus stearothermophilus cells, 5 mM 2′-deoxyinosine, 5 mM thymine, 20 units of xanthine oxidase (from buttermilk) in 10 ml of 50 mM ammonium acetate buffer (pH 5.5). The conversions were run at 55° C. for 1 hour. The reaction mixture was centrifuged and then filtered using an Amicon Ultrafiltration device (YM-3 membrane) and the products were separated and analyzed by HPLC (C-18 column) in 5% methanol and 5 mM phosphate buffer at pH 4.6 using a flow rate of 0.5 ml/ min. Thymidine was isolated in 68% yield (90% conversion).
