title: Enzymatic synthesis of purine 2'-deoxyriboside and its properties as an inhibitor of adenosine deaminases from calf intestinal mucosa and Bacillus cereus.
abstract: Enzymatic synthesis of purine 2'-deoxyriboside was obtained by reacting purine with excess 2-deoxy-alpha-D-ribose-1-phosphate in the presence of commercial bovine nucleoside phosphorylase; the product was isolated by semipreparative reverse phase HPLC with an overall 62% yield. Purine 2'-deoxyriboside was shown to behave as a competitive inhibitor of adenosine deaminase from calf intestinal mucosa and Bacillus cereus, with apparent Ki values of 4.5 and 8.5 microM, respectively.
