Research

NMR and Structure of Membrane Peptides

NMR spectroscopy, complemented by a range of biophysical techniques, is being used to determine the structure and dynamics of membrane polypeptides to determine their mechanism of activity. Currently our main focus is the structure and interactions of amyloid peptides from Alzheimer’s disease, pore-forming toxins and antibiotic peptides in model biological membranes. The results of our research provide insights into the biophysical chemistry of membrane-active peptides and proteins relevant to disease states and their possible treatments.

Solid-state NMR experiments have been designed for the structural determination of molecular systems that do not lend themselves to solution-state NMR and crystallographic methods, including crystalline powders and biological membranes. Our primary research interest is the determination of the structure and dynamics of membrane components in situ. Using solid-state NMR, we have determined the molecular structure of the antibiotic gramicidin A and the bee toxin melittin within phospholipid membranes. Together with researchers from CSIRO, industry and other international laboratories, we study biological macromolecules, geopolymers and ionic liquids with a range of pharmaceutical and industrial applications.
