Nullclines for multistable regimes. Besides bistability, also multiple steady states may occur within narrow intervals of intermediate LatA levels. In (A) and (B), the nullclines of two such cases are displayed in the (b, d)-phase plane. The stable fixed points are marked by filled circles, unstable fixed point by open circles. The G-actin concentrations are (A) g = 0.915, and (B) g = 0.828. For the other parameters see the caption of Figure 3.
