The structural transition of a double helical DNA from B-DNA to Z-DNA, B-Z transition, has been received growing attention because of its potential roles in biological systems and its applicability to nanobiotechnology. It was known that the B-Z transition is induced by cationic molecules. However, there are only a few reports describing cationic polymers as potential B-Z inducers. In this study, we demonstrated that cationic comb-type copolymer, poly(L-lysine)-graft-dextran, induced the B-Z transition in which distinct intermediate formation was involved. Furthermore, we suggested that the grafted-dextran plays an important role in the B-Z transition.
