From adenosine 1, 2′-deoxyadenosine 3 and 3′-deoxyadenosine 5 all the acetates were prepared by lipase-catalyzed reactions. Only the acetates with free 5′-hydroxy group were deaminated by adenosine deaminase (ADA), confirming the crucial role of 5′-OH for the enzyme activity.
从腺苷1,2'-脱氧腺苷3和3'-脱氧腺苷5个所有乙酸盐是由脂肪酶催化的反应制备。只有带有游离5'-羟基的乙酸盐才被腺苷脱氨酶(ADA)脱氨,这证实了5'-OH对酶活性的关键作用。
