My research focuses on the development and application of multidimensional and multinuclear solid-state NMR techniques to elucidate the structure and dynamics of membrane proteins and other biological macromolecules. In the area of membrane proteins, we are particularly interested in the biophysical chemistry and mechanisms of action of ion channels and curvature-inducing membrane proteins such as viral fusion proteins and antimicrobial peptides. Our research has elucidated the proton-conduction mechanism and drug-inhibition mechanism of influenza M2 proteins, the oligomeric structure and membrane-disruptive mechanism of β-hairpin antimicrobial peptides, and the conformation and dynamics of channel-forming colicin Ia for its spontaneous insertion into the lipid membrane. We also investigate the structure and dynamics of complex polysaccharides such as cellulose, hemicellulose, and pectins in plant cell walls and amyloid fibrils involved in neurodegenerative diseases.
To answer these biophysical questions, we develop a wide range of solid-state NMR techniques such as novel isotopic labeling strategies, multidimensional correlation techniques, polarization transfer pulse sequences, and computational methods. These new techniques allow efficient assignment of protein NMR spectra, increase the distance range of NMR from angstroms to nanometers, probe the insertion depth of membrane proteins, measure protein orientation in phospholipid bilayers, and detect intermolecular binding such as protein-drug, protein-cholesterol and protein-polysaccharide binding. These methods have allowed us to obtain detailed mechanistic insights about proteins and carbohydrates that cannot be obtained from any other high-resolution structural techniques.
