Scale bar: 5 μm.I: Wild type, mps1-3, mps1-3 spc105-18, and mps1-3 GLC7-24 cells were synchronised in G1 with α-factor at 25°C and then released at 32°C in the presence of nocodazole (note that the presence of 3HA tags at the C-terminus of Mps1-3 slightly decreases the maximal temperature of suppression). Cells were collected after 90 minutes and fixed with formaldehyde for ChIP-seq analysis. ChIP sequence reads were normalised against sequence reads from corresponding input samples, and relative enrichment is plotted for chromosome III around the centromere (see the centromeric regions of all 16 yeast chromosomes in Fig. S5). Y‐axis shows enrichment values (linear scale, range is 0-10). Values below 1.5 are shown in grey, and values above 1.5 (i.e. sequences enriched in ChIP samples) are red coloured.

Fold-changes relative to ESCs were calculated based on bulk RNA-seq data  C) Oxygen consumption rate of ES (blue line) and 2-cell-like cells (green line). Assay medium was formulated to recapitulate standard ES cell culture conditions and contained glucose, L-glutamine and pyruvate. Basal, maximal (FCCP-induced) and non-mitochondrial (Rotenone and Antimycin-A mediated) respiratory rates are indicated. A representative graph of 3 independent biological replicates performed on the Seahorse extracellular flux analyser is shown. Due to the low number of 2-cell-like cells available, compared to ESCs, one technical replicate of the former was analysed per biological replicate, while three or more technical replicates were performed for the latter.

Figure 2Glycolytic flux of wildtype (WT) and TM6 strains strongly correlates with fructose-1,6-bisphosphate (FBP) concentration. The glycolytic flux is reported here as the flux between the metabolites fructose 6-phosphate (F6P) and FBP. Glycolytic fluxes were obtained on the basis of physiological and metabolome data, and via a novel method to estimate intracellular fluxes (Niebel et al, 2019). While on high glucose, the WT strain accomplishes a high glucose uptake rate (and thus glycolytic flux), the mutant strain (TM6) only generates a low glucose uptake (and thus glycolytic flux). On maltose, also the mutant strain achieves a high glycolytic flux, since maltose is transported by a separate transporter (Chang et al, 1989). To assess the linear correlation between the FBP concentration and the glycolytic flux across the studied conditions, we implemented Pearson's correlation analysis assisted by bootstrapping. Specifically, we used in total 53 FBP concentration measurements corresponding to six different metabolic conditions (combinations of strains and carbon sources), biological and technical replicates. We paired each of these FBP measurements with the mean and standard deviation of the model-derived glycolytic flux (A) in the corresponding metabolic condition. We assumed the normal distribution of the flux and growth rate with the given mean and standard deviation in every condition, and implemented ordinary nonparametric bootstrapping with 100,000 iterations by randomly sampling values with replacement from the 53 FBP measurements and flux or growth-rate distributions to calculate the correlation statistics.FBP concentration as a function of cellular growth rate shows weaker correlation. For metabolite levels and growth rates, error bars correspond to the standard deviation between three independent experiments; for glycolytic fluxes to the mean and standard deviations of the sampled flux solution space (cf. Methods). The carbon sources were used at a final concentration of 10 gL-1 and are indicated: Glucose (GLU); Galactose (GAL); Maltose (MAL) and Pyruvate (PYR). To assess the linear correlation between the FBP concentration and the growth rate (B) across the studied conditions, we implemented Pearson's correlation analysis assisted by bootstrapping. Specifically, we used in total 53 FBP concentration measurements corresponding to six different metabolic conditions (combinations of strains and carbon sources), biological and technical replicates. We paired each of these FBP measurements with the mean and standard deviation of the growth rate (B) in the corresponding metabolic condition.

Figure 4CggR intracellular abundance in the wildtype (WT) strain on glucose strongly varies with the promoter used. The CggR intracellular levels were quantified by proteomics in steady-state cultures grown in minimal media with glucose as carbon source at a final concentration of 10 gL-1. Error bars represent the standard deviation of at least three replicate experiments.The relative abundance of CggR (normalized to the abundance measured on glucose and the same promoter) is almost constant with PTEFmut7 across multiple growth rates in WT and TM6 cells, but not with PTEFmut2 and PCMV. The CggR intracellular levels were quantified by proteomics in steady-state cultures grown in minimal media with glucose, galactose, maltose or pyruvate as carbon sources at a final concentration of 10 gL-1. WT data includes all three promoters, whereas TM6 only includes the PTEFmut2 and PTEFmut7 data. Error bars represent the standard deviation of at least three replicate experiments.
Figure 5Thermal shift assays were used to determine the melting curves of wild-type CggR and mutants. Error bars correspond to the standard deviation of at least five replicates.CggR-FBP affinity constants (KD's) of the wildtype and mutant variants, determined by fitting a simple cooperative binding model to the melting curves data. Error bars indicate the 95% confidence intervals.Quantification of CggR binding to DNA. The CggR bound to DNA fraction was calculated by dividing the intensity of the protein-DNA complex band by the total DNA. The background-subtracted total intensities of the CggR-DNA complex and the free-DNA bands were assessed with ImageJ. Error bars correspond to the standard deviation of three replicate experiments for the mutants and six for the wildtype.
Figure 6The four reporter plasmids were transferred to the wildtype strain containing the CggR (R250A) under the control of the PTEFmut7. The strength of the four promoters was assessed by quantifying YFP (FL1) and mCherry (FL3) fluorescence in exponentially growing wildtype cells in minimal medium with 10 g l-1 glucose. The FL1 and FL3 fluorescence shown is the non-background corrected median of 100 000 cell events. The non-FL control is the signal from a wildtype strain grown under the same conditions. The background fluorescence, assessed by the wildtype harboring the YCplac33 plasmid, was substracted from FL1 and FL3. The final reporter activity is the ratio of the background-corrected YFP and mCherry values. Error bars represent the standard deviation of three independently determined ratios from three replicate experiments.Reporter activity of the sensor across (D) multiple FBP levels Reporter activity is given by the YFP/mCherry ratio, calculated through the quantification of YFP and mCherry fluorescence along culture time using flow cytometry. Both YFP and mCherry fluorescence levels were first corrected for background using the same strains harboring the YCplac33 plasmid (Appendix Table S8). The control is the wildtype and TM6 strains expressing only the reporter plasmid without CggR. Error bars represent the standard deviation of at least three replicate experiments.Reporter activity of the sensor across glycolytic fluxes. The glycolytic flux is reported as the flux between the metabolites fructose 6-phosphate (F6P) and fructose-1,6-bisphosphate (FBP). Glycolytic fluxes were here estimated on the basis of physiological and metabolome data and a novel method to estimate intracellular fluxes (Niebel et al, 2019). Reporter activity is given by the YFP/mCherry ratio, calculated through the quantification of YFP and mCherry fluorescence along culture time using flow cytometry. Both YFP and mCherry fluorescence levels were first corrected for background using the same strains harboring the YCplac33 plasmid (Appendix Table S8). The control is the wildtype and TM6 strains expressing only the reporter plasmid without CggR. Error bars represent the standard deviation of at least three replicate experiments.Fraction of CggR bound to FBP across FBP concentrations. The red arrows indicate the shift in the percentage of CggR bound to FBP achieved in the R250A variant. The percentage of CggR molecules bound to FBP was calculated after normalizing the Tm values for unbound/bound state using the Tm at 0 mM FBP as unbound and at 36 mM (corresponding to maximum FBP concentration used) as total bound states. The curve fitting of the normalized values of CggR fraction bound to FBP was performed using a one-site specific binding model in GraphPad. The solid line corresponds to the wildtype CggR and the dashed line to the R250A variant. Vertical lines delimit the physiological FBP range.
