Zipping dynamics of semiflexible polymersFabian Heisterkamp and •Jan Kierfeld — Technische Universität Dortmund, Fakultät Physik, Otto-Hahn-Str. 4, 44227 Dortmund, Germany

The adhesion or zipping of two polymers plays an important role in many biological processes, for example the formation of filament bundles in the cytoskeleton. We investigate the dynamics of a zipping process with polymer ends attached to two large beads using Brownian dynamics simulations and analytical arguments. In the limit of large adhesion we find circular trajectories of the end beads. Simulations for realistic parameter values exhibit deviations due to bending forces and buckling.
