We report the photoinduced 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 photoinduced repair of a thymine dimer.
我们报道了通过含咔唑核苷（K）的寡脱氧核苷酸（ODN）对掺入DNA双链体中的胸腺嘧啶二聚体进行光诱导修复。荧光猝灭测量证明了K与胸腺嘧啶二聚体之间发生了电子转移。K作为胸腺嘧啶二聚体光诱导修复的良好电子供体。
