The production rates of YFP and mCherry are uncoupled during the cell cycle in the biosensor-expressing strain (F), which reflects the cell-cycle dynamics of intracellular FBP concentration and glycolytic flux. In a control strain, lacking CggR, the production rates of YFP and mCherry are coupled (G). The uncoupling was calculated for individual cell-cycle trajectories as the difference between the YFP and mCherry production rates normalised to have the same scale (see more details in Materials and methods; Appendix Figure S10). Each curve represents the mean across the indicated number of cell cycles in a replicate experiment. The corresponding shaded areas denote the 95% confidence intervals of the means (bootstrapping with 5 000 iterations). We smoothed the single-cell-cycle trajectories of YFP and mCherry signals as well as cell volume via the Gaussian process regression, and used these trajectories to derive the YFP and mCherry production rates, accounting for fluorescent-protein maturation in a first-order kinetics model. To align the cell-cycle trajectories and to calculate the phase, we used the array of three cell cycle events E {cytokinesis (cyt), budding, next cyt} as reference points. The cell cycles used for the analysis had the duration in the interval between 150 and 300 minutes, with the mean duration presented in parentheses for each replicate experiment. The cells belonged to the TM6 strain and were cultivated on 20 gL-1 glucose in the microfluidic device.
