Long-distance radical cation migration in duplex DNA: the effect of contiguous A.A and T.T mismatches on efficiency and mechanism.

Journal of the American Chemical Society - 24 Dec 2003

Schlientz Nathan W, Schuster Gary B

Abstract excerpt

A series of DNA oligomers was prepared. Each oligomer contained an anthraquinone group (AQ, sensitizer) covalently linked at a 5'-end and two GG steps that surrounded a variable region. The variable region was composed of A.T base pairs or A.A or T.T mismatches. Irradiation of the AQ injected a radical cation (hole) into the DNA that migrated through the duplex, being trapped by reaction with H2O of O2 at the GG...
