, 2008?and?Loose et?al., 2011a) and to verify the sequestration mechanism experimentally. As a preliminary result, we note that the current model sustains bands of synchronous traveling waves as observed in?vitro (Loose et?al., 2008?and?Loose et?al., 2011a), even without extending the reaction scheme (Figure?1A) by the suggested nonlinear detachment (Loose et?al., 2011a) of Min proteins or cooperative MinE recruitment (Loose et?al., 2008). On a broader check details perspective, the presented theoretical formalism enables the investigation of protein dynamics in?vivo and in?vitro with explicit account for the underlying system geometries and?nonlinear bulk-boundary couplings. Examples are intracellular polarization mechanisms driven by reaction-diffusion processes, e.g., in Caenorhabditis elegans ( Goehring et?al., 2011) or Saccharomyces cerevisiae ( Johnson, 1999). All time-dependent computations were performed with finite element methods on a triangular mesh using Comsol Multiphysics 3.5a. As initial conditions, linear profiles along the cell's long axis with varying slopes and small random fluctuations at each mesh site were chosen. In these cases all particles were initially located in the bulk. The traveling wave initial condition used in simulations with filamentous cells was obtained by choosing a low MinD recruitment rate about kdD=0.03��m2/skdD=0.03��m2/s and picking the traveling wave solution at a time step where the total MinD concentration was maximal in one cell half. Extended Experimental Procedures For an ellipse with major flupentixol semi-axis ra ?, minor semi-axis rb ?, and linear eccentricity d=ra2?rb2, we choose orthogonal elliptical coordinates given by x=dcosh(��)cos(��) y=dsinh(��)sin(��),with �� > 0 and 0?�� ��?find more for cytosolic particles, and v for membrane particles: equation(S2) ?tu=Dc?2u?��u,?tu=Dc?2u?��u, equation(S3) ?tv=Dm?��2v+g(u,v),with boundary conditions: equation(S4) Dc?��u|��=��0=f(u,v).Dc?��u|��=��0=f(u,v). The degradation term ��u in Equation 1 accounts for nucleotide exchange, and can be set to zero in order to obtain the bulk solutions for the different species, e.g., the time evolution of cytosolic MinD uD?= uDT?+ uDD is governed by diffusion alone as the reaction terms cancel. Then the time evolution of MinD-ATP is obtained from uDT?= uD ? uDD.
