covalent attachment of recombinant Lactobacillus reuteri 2'-deoxyribosyltransferase to Sepabeads EC-EP303. The immobilized enzyme retains 50% of its maximal activity after 17.9 h at 60°C, and 96% activity is observed after storage at 40°C for 110 h. Immobilized enzyme can be recycled for 26 consecutive batch reactions in the synthesis of 2,6-diaminopurine-2'-deoxyriboside with negligible loss of catalytic activity and can be employed in the enzymatic synthesis of different natural and therapeutic nucleosides such as 5-ethyl-2'-deoxyuridine and 5-trifluorothymidine

immobilization of 2'-deoxyribosyltransferase from Lactobacillus reuteri on Sepabeads. Immobilized enzyme activity is enhanced 1.21.4fold at 20% of methanol, ethanol, 2-propanol, diethylene glycol, and acetone, and at 10% and 30% acetonitrile. Highest increased activity is also obtained in presence of 20% acetonitrile. Immobilized enzyme is successfully used in the synthesis of 2'-deoxyxanthosine and 2'-deoxyguanosine using 2'-deoxyuridine as sugar donor and the corresponding poor water-soluble base in the presence of 30% of methanol, ethanol, 2-propanol, ethylene glycol, acetonitrile, and DMSO, giving high nucleoside yields at 4 h
