Particle-based computer simulations of the Min-system — •Nikolas D. Schnellbächer1,2, Artemij Amiranashvili1,2, and Ulrich S. Schwarz1,2 — 1BioQuant, Heidelberg, Germany — 2Institute for Theoretical Physics, Heidelberg University, Heidelberg, Germany
E. Coli and similar bacteria use a system of so-called Min-proteins to find the middle for cell division. The Min-system can also be reconstituted outside the cellular context and then leads to a variety of dynamic oscillatory patterns whose details depend both on global compartment geometry and local binding kinetics. We use three-dimensional and stochastic particle-based computer simulations to predict pattern formation as a function of geometry. We investigate the stability of different oscillation modes on the same pattern and the stochastic switching between them. We find that the number of membrane bound molecules is independent of the volume to area ratio and establish requirements for a sharp MinE-ring formation, depending on different MinE-binding modes.
