[摘要]:opposite the abasic site in DNA duplexes (5'-TCC AGX GCA AC-3'/3'-AGG TCN CGT TG-5', X = AP site (Spacer C3), N = A, T, C and G) than the other three nucleobases with a dissocn. const. Kd of ca. 1.0 mM; substituted Me groups enhance the binding affinity to A and the selectivity for A over T, compared to the parent mol., lumazine. |
