1H NMR study on equilibrium between parallel G-quartet structures.
Structural transition of parallel G-quartet formed by d(TG4T) are induced by monovalent cations. In the presence of K+ ion, G-quartet takes a single conformation, while in the presence of Na+ ion, the equilibrium between more than three conformations were observed.
