Methods and compositions regarding autocatalytic DNA strand exchange with a pre-defined target DNA are described herein. Specifically, single stranded DNA or double stranded DNA construct comprising preferably four definable sequences facilitate phospho-diesterase hydrolysis reactions and subsequent phosphodiesterification reactions or a transesterification reaction between the construct and a target DNA. The reactions require no mediation by protein catalytic mechanisms and are useful for therapeutic applications regarding genetically related diseases.
本文介绍了与预先确定的目标 DNA 进行自催化 DNA 链交换的方法和组合物。具体来说,由优选的四个可定义序列组成的单链 DNA 或双链 DNA 构建体可促进
磷酸二酯酶水解反应以及随后的
磷酸二酯化反应或该构建体与目标 DNA 之间的酯交换反应。这些反应不需要蛋白质催化机制的调解,可用于治疗与
基因有关的疾病。
