DNA Hairpins Containing a Diaminostilbene Derivative as a Photoinduced Electron Donor for Probing the Effects of Single-Base Mismatches on Excess Electron Transfer in DNA
To investigate the effects of local structural disorder induced by a single-base mismatch on excesselectrontransfer (EET) in DNA, a novel hairpinDNA containing diaminostilbene (DAS) as a photoinducible electron donor has been developed. It was clearly demonstrated that EET efficiency depends on the electron injection modes from the electron donors and redox properties of the mismatched bases.
