It was found that photoreduction of 5-bromouracil (BrU) occurs at 5'-ATBrU-3' sequence more efficiently than 5'-ABrU-3'. We introduced 5'-GG-3' sequence at the 5'-side of 5'-ATBrU-3' sequence and 5'-ABrU-3' sequence and investigated their photoreduction. As a result, dIz, an oxidation product originated from guanine cation radical, was detected.
