脱氧核酶(DNA酶; DNAzymes)是催化DNA序列。使用体外选择技术,已经鉴定出催化RNA切割、RNA连接和越来越多的其他化学反应的单个脱氧核酶。DNA酶已在体外用于诸如生物化学RNA操作和金属离子、小有机化合物、寡核苷酸和蛋白质的分析测定的应用。脱氧核酶也已被用作体内治疗剂以破坏特异性mRNA靶标。虽然许多概念和实际的挑战仍有待解决,脱氧核酶有实质性的承诺,有助于有意义的应用在体外和体内。
Deoxyribozymes (DNA enzymes; DNAzymes) are catalytic DNA sequences. Using the technique of in vitro selection, individual deoxyribozymes have been identified that catalyze RNA cleavage, RNA ligation, and a growing range of other chemical reactions. DNA enzymes have been used in vitro for applications such as biochemical RNA manipulation and analytical assays for metal ions, small organic compounds, oligonucleotides, and proteins. Deoxyribozymes have also been utilized as in vivo therapeutic agents to destroy specific mRNA targets. Although many conceptual and practical challenges remain to be addressed, deoxyribozymes have substantial promise to contribute meaningfully for applications both in vitro and in vivo.
