Neocarzinostatin acts as a sensitive probe of DNA microheterogeneity: switching of chemistry from C-1' to C-4' by a G.T mismatch 5' to the site of DNA damage.
The diradical form of thiol-activated neocarzinostatin chromophore resides in the minor groove of DNA, where it has access to hydrogen atoms at the C-5', C-1', and C-4' positions of deoxyribose on each strand. In a dodecamer oligodeoxyribonucleotide containing the sequence AGC.GCT, a...
