The transition state of coupled folding and binding for a flexible β-finger.

Abstract excerpt

Flexible and fully disordered protein regions that fold upon binding mediate numerous protein-protein interactions. However, little is known about their mechanism of interaction. One such coupled folding and binding occurs when a flexible region of neuronal nitric oxide synthase adopts a β-finger structure upon binding to its protein ligand, a PDZ [PSD-95 (postsynaptic density protein-95)/Discs large/ZO-1] domain...
