We report the catalytic repair of a thymine dimer incorporated in a DNA duplex via oligodeoxynucleotide (ODN) containing carbazole nucleoside (K). The occurrence of an electron transfer between K and thymine dimer is evidenced by fluorescence quenching measurements. K acts as a good electron donor for the catalytic repair of a thymine dimer.
我们报告了通过含有
咔唑核苷(K)的寡脱氧核苷酸(ODN)对包含在 DNA 双链中的胸腺
嘧啶二聚体进行催化修复的情况。荧光淬灭测量证明了 K 和胸腺
嘧啶二聚体之间发生了电子转移。K 是胸腺
嘧啶二聚体催化修复的良好电子供体。
