artificial components into RNA by transcription, an efficient, unnatural base pair between 2-amino-6-(2-thiazolyl)purine (denoted as v) and 2-oxo(1H)pyridine (denoted as y) was developed. The substrates of y and 5-substituted y were site-specifically incorporated into RNA by T7 RNA polymerase opposite v in templates. The efficiency and fidelity of the v-y pairing in transcription were as high as those of the
为了通过转录将人工成分定点掺入 RNA,在 2-amino-6-(2-thiazolyl)purine(表示为 v)和 2-oxo(1H)pyridine(表示为 y ) 已开发。y 和 5 取代 y 的底物通过 T7 RNA 聚合酶在模板中与 v 相对地位点特异性地整合到 RNA 中。vy 配对在转录中的效率和保真度与天然 AT(U) 和 GC 配对一样高。此外,含有两个相邻 y 碱基的 RNA 也从含有两个 v 碱基的 DNA 模板转录而来。这种特定的转录允许大规模制备人工 RNA,并且可以与其他系统结合以同时将几种不同的成分整合到转录物中。
