Figure 6.

Stochastic fluctuation of oscillation of individual KaiC hexamers. Frequency of the P_i release, f ₀, is (a) f ₀ = 2.4 h⁻¹ and (b) f ₀ = 1.2 h⁻¹. In top panels, simulated oscillations, D _k(t), of five KaiC hexamers are superposed; these hexamers were arbitrarily chosen from the ensemble of N = 1000 hexamers. Oscillations of different hexamers are shown with different colors. In bottom panels, the simulated oscillation of the ensemble, $\overline{D}(t)$, is shown. Parameter values other than f ₀ are the same as explained in the caption of Fig. 2.
