Peptide – lipid bilayer interactions

Ph.D. student Keon Reid has been using molecular dynamics simulation to understand the behavior of the anti-cancer/anti-microbial peptide SVS-1 in collaboration with members of the Dyer group.  A manuscript describing Keon’s simulations and experiments by Dr. Caitlin Davis on this peptide has recently been submitted for publication:

K. A. Reid, C. M. Davis, R. B. Dyer, and J. T. Kindt, “Binding, folding, and insertion of a beta-hairpin peptide at a lipid bilayer surface: Influence of electrostatics and lipid tail packing.”  Submitted to Biochim. Biophys Acta – Biomembranes 8/2017.
