| + | Aptides, a novel class of high-affinity peptides, recognize diverse molecular targets with high affinity and specificity. The solution structure of the aptide APT specifically bound to fibronectin extradomain B (EDB), which represents an unusual protein-protein interaction that involves coupled unfolding and binding, is reported. APT binding is accompanied by unfolding of the C-terminal beta strand of EDB, thereby permitting APT to interact with the freshly exposed hydrophobic interior surfaces of EDB. The beta-hairpin scaffold of APT drives the interaction by a beta-strand displacement mechanism, such that an intramolecular beta sheet is replaced by an intermolecular beta sheet. The unfolding of EDB perturbs the tight domain association between EDB and FN8 of fibronectin, thus highlighting its potential use as a scaffold that switches between stretched and bent conformations. | ||
