单核苷酸多态,无论是遗传的还是由于自发的DNA损伤,都与许多疾病有关。开发定点核苷酸修饰的工具有朝一日可能会提供一种改变疾病多态的方法。在这里,我们描述了一种名为F-8的新型脱氧核酶的体外筛选和特性,它催化胸苷特异性的核苷酸切除。被F-8切割产生DNA修饰酶识别的3‘-和5’-磷酸末端,修复靶向脱氧核苷酸,同时保持序列其余部分的完整性。这些结果说明了DNAzyme作为DNA操作工具的潜力。
Single-nucleotide polymorphisms, either inherited or due to spontaneous DNA damage, are associated with numerous diseases. Developing tools for site-specific nucleotide modification may one day provide a way to alter disease polymorphisms. Here, we describe the in vitro selection and characterization of a new deoxyribozyme called F-8, which catalyzes nucleotide excision specifically at thymidine. Cleavage by F-8 generates 3′- and 5′-phosphate ends recognized by DNA modifying enzymes, which repair the targeted deoxyribonucleotide while maintaining the integrity of the rest of the sequence. These results illustrate the potential of DNAzymes as tools for DNA manipulation.
