Similarities in sugar sensing responses in the three biosensors. GFP fold change is normalized to the fluorescence at 0 h after incubation on YPFG. Green lines with triangle markers show the biosensor responses for different concentrations of intracellular d-glucose-6-phosphate levels [mg L−1] modulated by PGI1 deletion and variation of media composition. Blue dashed lines with square markers show the biosensor responses to various concentrations of extracellular d-glucose [g L−1] (adapted from Brink et al. 2016 [17]). d-glucose-6-phosphate graphs are cropped for clarity; uncropped graphs can be found in Additional file 1: Fig. S5
