Dynamics and interactions of glycoconjugates probed by stable-isotope-assisted NMR spectroscopy

Abstract

Unique advantages offered by nuclear magnetic resonance (NMR) spectroscopy provide high-resolution information not only on structures but also on dynamics and interactions of glycoconjugates in solution. These benefits are further enhanced by applying stable-isotope-labeling techniques, which we have developed. Our stable-isotope-assisted NMR analyses of immunoglobulin G-Fc glycoproteins and the glycopeptides derived therefrom are here presented in terms of the dynamics and interactions of glycoconjugates.
