Oscillation space predicted by the oscillator model in the absence of catalysis: the region coloured in a gradient from red to green indicates the ranges of [ 4 ] and [ 2 ] predicted to support sustained oscillations with [ 3 ] = 30 mM, [ 5 ] = 5 mM and a space velocity of 10 −4 s −1 ; colour coding indicates the predicted period. In the light blue region, dampened oscillations are predicted to take place and in the uncoloured region no oscillations occur. Squares represent oscillator experiments carried out without catalysis, as in Fig. 3b ; filled squares indicate where experiments found sustained oscillations and open squares dampened oscillations. Diamonds represent oscillator experiments carried out with catalysis; red diamonds indicate where experiments found sustained oscillations and white diamonds dampened oscillations.
