Characterization of distamycin A binding to damaged DNA.


We previously reported that distamycin A, a natural antibiotic known as a minor groove binder, could bind to DNA duplexes containing the (6-4) photoproduct formed at its target site, whereas the binding was not observed for duplexes containing the cis-syn cyclobutane pyrimidine dimer in the same sequence context. In this study, we have further analyzed the… (More)
