Identification of mixed di-cation forms of G-quadruplex in solution
Multinuclear NMR study has demonstrated that G-quadruplex adopted by d(G3T4G4) exhibits two cation binding sites between three of its G-quartets. Titration of tighter binding K+ ions into the solution of d(G3T4G4)2 folded in the presence of NH4+15 ions uncovered a mixed mono-K+-mono-NH4+15 form that...
