(6-4) photoproduct DNA photolyase mechanistic studies using s5-(6-4) photoproducts
Abstract
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.
