Through the use of photoaffinity-labeling reagents, several new insights into nucleic acid interactions have been obtained, for example in DNA replication and repair. In most known photoprobes, the applied light-sensitive functionalities are placed directly at the nucleobase or are attached via linkers to either the nucleobase or the phosphate backbone. Here we describe the first photoprobe that bears a light-sensitive aryl(trifluoromethyl)diazirine at the sugar moiety of a DNA oligonucleotide. We devised a route for the synthesis of the modified nucleoside and its incorporation into an oligonucleotide. The photoactive species was proven to be stable under the conditions employed in routine automated DNA synthesis. The modified oligonucleotide was shown by subsequent photolabeling studies of human DNA polymerase beta to form a covalent complex to the enzyme upon irradiation with near-UV light.</dcterms:abstract> <dcterms:issued>2006-12-04</dcterms:issued> <dc:date rdf:datatype="http://www.w3.org/2001/XMLSchema#dateTime">2016-05-20T12:56:38Z</dc:date> <dc:contributor>Di Pasquale, Francesca</dc:contributor> <dc:creator>Liebmann, Meike</dc:creator> <dc:language>eng</dc:language> <dc:creator>Marx, Andreas</dc:creator> <bibo:uri rdf:resource="https://kops.uni-konstanz.de/handle/123456789/34049"/> <dcterms:title>A New Photoactive Building Block for Investigation of DNA Backbone Interactions : Photoaffinity Labeling of Human DNA Polymerase β</dcterms:title> </rdf:Description> </rdf:RDF>
