Nullclines for the mono- and bistable regimes. Nullclines in the (b, d)-phase plane for (A) high, (B) medium, and (C) low concentration of G-actin, corresponding to low, medium, and high levels of LatA, respectively. The stable fixed points are marked by filled circles, unstable fixed point by open circles. The G-actin concentrations are (A) g = 1, (B) g = 0.872, and (C) g = 0.795. The other parameters are 
, kj2 = 23.5, kj3 = 6, kj4 = 0.5 and kj5 = 1 with j = b, d.
