这两个酶都显示了对单链DNA和双链DNA的酶切活性,但它们都需要二价阳离子(Mg2+,Ca2+)发挥活性,并且他们的活性都会受到螯合剂的抑制。
Both enzymes showed activities either on ssDNA or dsDNA . They required a divalent cation ( Mg2 + , Ca2 + ) and its activity was inhibited by chelating agents .

没有目标物腺苷存在时,核酸适体折叠成发夹结构,在茎部形成一个酶切双链区,酶切后二茂铁脱离电极表面,没有二茂铁的响应电流信号产生。
In the absence of target adenosine , the aptamer can fold into a hairpin structure and form a cleavable double-stranded region . Fc species are capable of being removed from the electrode surface by treatment with endonuclease , and no peak current is observed .
