Interaction of Model Proteins in a Lipid Bilayer under Surface Tension — •Jörg Neder1, Beate West2, and Peter Nielaba1 — 1Department of Physics, University of Konstanz, 78457 Konstanz — 2Department of Physics, University of Bielefeld, 33615 Bielefeld
Recently O. Lenz and F. Schmid [1] introduced a simple coarse-grained model to study lipid layers and their phase transitions. Using an extension of this model [2] we are investigating the influence of an applied surface tension to a bilayer membrane. One aim of our work is the comparison of lipid-mediated protein-protein interaction between the tensionless state of the bilayer and states with non-vanishing surface tension. Furthermore, we are interested in developing a method for calculating the chemical potential of incorporated model proteins.
