Angew Chem Int Ed Engl. 2014 Jun 23;53(26):6734-7. doi: 10.1002/anie.201402370. Epub 2014 May 21.

Abstract

5-[(2-Nitrobenzyl)oxymethyl]-2'-deoxyuridine 5'-O-triphosphate was used for polymerase (primer extension or PCR) synthesis of photocaged DNA that is resistant to the cleavage by restriction endonucleases. Photodeprotection of the caged DNA released 5-hydroxymethyluracil-modified nucleic acids, which were fully recognized and cleaved by restriction enzymes.

Keywords: DNA; DNA polymerase; nucleotides; photocaging; protective groups.
