Upper, single filament length against the corresponding intrinsic size N c . The blue dashed line is the theoretical L={N}{{{\rm{c}}}}(sigma) ( sigma = 5 nm). Lower, average treadmilling velocity v of a filament against the corresponding growth rate r on . The blue dashed line is the theoretical v={r}{{{\rm{on}}}}(sigma) . In both graphs, each point is the steady-state average over 20 replicas of single-filament simulations with error bars for the standard error of the average. The grey dashed lines correspond to the fluorescence microscopy experiments of in vitro reconstituted E. coli FtsZ treadmilling filaments on SLBs at 1.25 microM (shaded areas for error). Purple triangles correspond to r on = 8 monomers per second and (tau)det = 5 s, which fit experimental measurements best and are used for the simulation data in c .
