摘要: S1核酸酶是一种高度单链特异的核酸内切酶,在最适的酶催化反应条件下,降解单链DNA或RNA,产生带5'-磷酸的单核苷酸或寡核苷酸。对双链DNA、双链RNA和DNA-RNA杂交体相对不敏感。目前,基于S1核酸酶内切酶的活性,搭载不同的信号输出及扩增方式,已经构建了一系列的生物传感器,实现了对金属离子、单链核苷酸、氨基酸等物质的检测,还能应用于核酸反应体系的纯化,多元化基因文库的构建等方面。首先从结构、性质方面介绍了S1核酸酶,并对近年来基于S1核酸酶介导的、具有代表性的生物传感器的组建及应用情况进行了综述;然后主要根据所检测的靶物质不同,对S1核酸酶介导的各种传感器进行了分类介绍;最后分析了目前S1核酸酶的研究现状,并且对未来S1核酸酶介导的生物传感器的发展方向进行了展望。

Abstract: The S1 nuclease is a highly single-stranded and specific endonuclease that degrades single-stranded DNA or RNA under optimal enzymatic conditions to produce single nucleotides or oligonucleotides with 5'-phosphate. It is relatively insensitive to double-stranded DNA,double-stranded RNA,and DNA-RNA hybrids. At present,based on the activity of S1 nuclease for carrying different signal outputs and amplification methods,a series of biosensors have been constructed to detect metal ions,single-stranded nucleotides,amino acids and other substances. Moreover,the S1 nuclease can be applied to the purification of nucleic acid reaction system,the construction of a multi-dimensional gene Library. In this paper,S1 nuclease is introduced from the aspects of structure to functions,and the representative biosensors mediated by S1 nuclease are summarized from the view of establishment and application. Then,based on the different target substances detected,various S1 nuclease-mediated sensors are classified and introduced. Finally,the current research status of S1 nucleases is analyzed,and the future development direction of S1 nuclease-mediated biosensors is prospected.
