  The Sugar Conformation Governs (6-4) Photoproduct Formation at the Dinucleotide Level

  摘要：

  The LNA dinucleotide mimic of TpT whose two-sugar puckers are locked in the C3'-endo conformation selectively produces the corresponding cyclobutane pyrimidine dimer under 254 nm irradiation. In the natural series (TpT) the sugar puckers are in a major C2'-endo sugar conformation and the (6-4) photoproduct is also produced. Consequently, this study demonstrates that the C2'-endo conformation of the sugar pucker is necessary for (6-4) photoproduct formation.
