pH-sensitive DNA switch

A pH-sensitive DNA nanoswitch, which folds into triplex under low pH and duplex under high pH.

Mechanism

Conventional base-pairing present in DNA between A-T and C-G are known as Watson-Crick base pairing denoted as "-", also known as complementary base pairing. However, another type of pairing exists as well, known as Hoogsteen base pairing. One of the bases of A-T or C-G is flipped, and hydrogen bonds hold them together as well. However, C·G hoogsteen bonds (denoted as "·")require protonation of Cytosineto form one essential hydrogen bond.
