pH-Dependent Capping Interactions Induce Large-Scale Structural Transitions in i-Motifs
[Image: see text] We study here a DNA oligonucleotide having the ability to form two different i-motif structures whose relative stability depends on pH and temperature. The major species at neutral pH is stabilized by two C:C(+) base pairs capped by two minor groove G:C:G:C tetrads. The high pH and...
