Two acyl-transfer catalysts were conjugated to thrombin-binding DNA aptamers to acylate thrombin. Modification occurred site-selectively on Lys (≫Ser) residues proximal to the respective aptamer-thrombin interface, was selective for thrombin in the presence of other proteins, and the activity of both DNA-catalysts could be controlled by an external trigger.
两个酰基转移催化剂被连接到凝血酶结合 DNA 适体上来酰化凝血酶。修饰选择性地发生在靠近各自适体-凝血酶界面的 Lys(≫Ser)残基上,在存在其他蛋白质的情况下对凝血酶具有选择性,并且两个 DNA 催化剂的活性都可以被外部触发控制。
