ABSTRACT
Quantitative DNase I footprinting shows that three designed peptides containing N-methylpyrrole (Py) moieties display different types of network-based allosteric communication in binding to DNA circuit type, incomplete-circuit type, and non-circuit type characterized by interstrand bidentate interactions. Positive cooperative binding of all three peptides to individual DNA binding sites is commonly observed. CD spectral characterization of the interaction between peptides and model undecanucleotide duplexes is consistent with the footprinting results and supports the allosteric model. This study provides insights relating to the interaction network nature of allostery in complex DNA-small molecule interactions.
