Fig. 4. Engineering the β-alanine-inducible system.

Fig. 4

a Schematic illustration of the different versions of the β-alanine-inducible system and their corresponding plasmid identifiers. Absolute normalised fluorescence of b E. coli and c P. putida carrying different versions of the β-alanine-inducible system–reporter construct in the absence (light purple and light blue) and presence (dark purple and dark blue) of 5 mM β-alanine. Single time-point RFP fluorescence measurements were taken 6 h after effector addition. Data are mean ± SD, n = 3, *p < 0.05, **p < 0.0001, unpaired two-tailed t-test. Source data are provided as a Source Data file.
