FIGURE 7.

The probability ρ(λ) for the transition state ensemble (P_B = 0.5) for the transition from A to B, where λ = n_A – n_B. (Top row, A) Exclusive switch. (Bottom row, B) General switch. The probability ρ(λ) is split into color-coded contributions from the three operator states; the area under each histogram gives the probability 〈N_OX〉 that the operator is bound to species X (the three areas thus sum to unity). The left panels correspond to the system with slow dimerization k_f = 0.1; the middle panels correspond to the system with the base-line parameters; the panels on the right corresponds to the system with fast operator binding k_on = 500.
