Construction and data

For the biosensor circuit Ph/HcaR, we created a library of RBS (Ribosome Binding Site) including B0031, B0032 and B0034 for tuning the expression level of reporter gene sfGFP. K1031420 is composed of three elements, Ph promoter activated by HcaR, RBS B0031 and reporter gene sfGFP (Fig 1a). Induction ratio was tested when K1031420 is in collocation with J23106-HcaR and J23114-HcaR, as shown in the dashed boxes (Fig 1b)

Fig 2 Construction and tunning of reporter circuit Ph-B0031-sfGFP. (a) The orange arrow represents Ph promoter activated by HcaR. The green oval stands for RBS B0031. sfGFP coding sequence is shown with dark blue, while terminator B0015 is in dark red. (b) Horizontal axis represents biosensor circuit adopting different combination of Pc promoter and RBS. Vertical axis stands for induction ratio. The dashed box refers to data for reporter circuit Pc-B0031-sfGFP in collocation with biosensor circuits J23106-HcaR and J23114-HcaR respectively.
