Biochemistry: Confinement and Stabilization of Fyn SH3 Folding Intermediate Mimetics within the Cavity of the Chaperonin GroEL Demonstrated by Relaxation-Based NMR
February 21, 2017
David S Libich 1, Vitali Tugarinov 1, Rodolfo Ghirlando 1, G Marius Clore 1 Abstract The interaction of two folding intermediate mimetics of the model protein substrate Fyn SH3 with the chaperonin GroEL, a supramolecular foldase/unfoldase machine, has been investigated by 15N relaxation-based nuclear magnetic resonance spectroscopy (lifetime line broadening, dark-state exchange saturation transfer, and relaxation dispersion). The two mimetics comprise C-terminal truncations […]
