  摘要：

  The exploitation of a unique thymidylyltransferase (Ep ) allows the rapid syntheses of thymidine and uridine 5'-(aminodeoxy-α-D-hexopyranosyl diphosphates), 5'-(acetamidodeoxy-α-D-hexopyranosyl diphosphates), and even 5'-(aminodideoxy-α-D-hexopyranosyl diphosphates), which are amino analogues of the products from the native reaction of Ep .
