Guanine to Inosine Substitution Leads to Large Increases in the Population of a Transient G·C Hoogsteen Base Pair

[Image: see text] We recently showed that Watson–Crick base pairs in canonical duplex DNA exist in dynamic equilibrium with G(syn)·C(+) and A(syn)·T Hoogsteen base pairs that have minute populations of ∼1%. Here, using nuclear magnetic resonance R(1ρ) relaxation dispersion, we show that substitution...
