title: Reversible photoligation of DNA via 5-vinyldeoxyuridine.
abstract: We report a novel non-enzymatic template-directed reversible photoligation of oligodeoxyribonucleotides (ODNs). In this photoligation system, a modified ODN containing 5-vinyldeoxyuridine at 5'-end reacts by photoirradiation at 366 nm with cytosine and thymine at the 3'-end of another ODN in the presence of a complementary template to yield a ligated ODN quantitatively. The ligated ODN can be split site-selectively to regenerate the parent ODN by photoirradiation at 302 nm.
