Peptide nucleic acid-DNA duplexes: long range hole migration from an internally linked anthraquinone. Armitage, B, Ly, D, Koch, T, Frydenlund, H, Orum, H, Batz, H G, & Schuster, G B Proceedings of the National Academy of Sciences of the United States of America, 94(23):12320–5, November, 1997. ![Peptide nucleic acid-DNA duplexes: long range hole migration from an internally linked anthraquinone.

Paper abstract bibtex The discovery that peptide nucleic acids (PNA) mimic DNA and RNA by forming complementary duplex structures following Watson-Crick base pairing rules opens fields in biochemistry, diagnostics, and medicine for exploration. Progress requires the development of modified PNA duplexes having unique and well defined properties. We find that anthraquinone groups bound to internal positions of a PNA oligomer intercalate in the PNA-DNA hybrid. Their irradiation with near-UV light leads to electron transfer and oxidative damage at remote GG doublets on the complementary DNA strand. This behavior mimics that observed in related DNA duplexes and provides the first evidence for long range electron (hole) transport in PNA-DNA hybrid. Analysis of the mechanism for electron transport supports hole hopping.
