Recently, KOD and its related DNA polymerases have been used for preparing various modified nucleic acids, including not only base-modified nucleic acids, but also sugar-modified ones, such as bridged/locked nucleic acid (BNA/LNA) which would be promising candidates for nucleic acid drugs. However, thus far, reasons for the effectiveness of KOD DNA polymerase for such purposes have not been clearly
最近,KOD及其相关DNA聚合酶已被用于制备各种修饰核酸,不仅包括碱基修饰核酸,还包括糖修饰核酸,如桥接/锁核酸(BNA/LNA),这将是有前景的核酸药物的候选者。然而,迄今为止,KOD DNA 聚合酶对此类目的有效的原因尚未明确阐明。因此,使用突变的 KOD DNA 聚合酶,我们在这里研究了它们在酶促掺入具有碱基/糖修饰的核苷酸类似物后的催化特性。实验数据表明,它们特有的动力学特性能够掺入各种修饰的核苷酸。在这些 KOD 突变体中,一个成功地连续掺入了具有 2'-ONHCH2CH2-4' 连接的桥接核苷酸。
