The facile photoreversal reaction, which occurs upon direct irradiation of the thioanalogue of the (6-4) photoproducts of DNA 3, and not from its corresponding Dewar derivative 4, to give the parent dinucleotide 1 models (6-4) photoproduct DNA photolyase repair activity.
在直接照射 DNA 的(6-4)光反应产物 3 的
硫代对映体而不是其相应的杜瓦衍
生物 4 时,会发生简便的光逆转录反应,生成母体二核苷酸 1 模型(6-4)光反应产物 DNA 光解酶修复活性。
