Elucidating slow binding kinetics of a protein without observable bound resonances by longitudinal relaxation NMR spectroscopy
Abstract We developed a new method to elucidate the binding kinetics kon and koff, and the dissociation constant KD (=koff/kon), of protein-protein interactions without observable bound resonances of the protein of interest due to high molecular weight in a complex with a large target protein. In our method, kon and koff rates are calculated from the analysis of longitudinal relaxation rates of free resonances measured for multiple samples containing different...
