that it is coordinatively saturated, rendering it catalytically inactive. Upon addition of an RNA or DNA strand that is complementary to the latent catalyst's oligonucleotide backbone, catalytic activity is induced, leading to a sevenfold increase in the formation of a fluorescent product, forged through a AuI -catalyzed hydroamination reaction. Further development of this catalytic system will expand

生物介质相容并且其反应性可以由小的互补核酸序列调节的AuI -DNA杂化催化剂的发现。通过发现新的AuI介导的碱基对,使得该催化体系得以发展。我们发现AuI结合了包含CT错配的DNA。在AuI-DNA催化剂的潜在状态下,AuI离子由于不匹配而被隔离,从而使AuI离子配位饱和,使其失去催化活性。在添加与潜在催化剂的寡核苷酸主链互补的RNA或DNA链时,诱导了催化活性,导致通过AuI催化的加
氢胺化反应伪造的荧光产物的形成增加了七倍。
