Construction and tunning

Pc promoter J23114 is selected to initiate the transcription of XylR. Based on this circuit, we constructed a library of RBS (Ribosome Binding Site) including B0031[1], B0032[2], B0033[3] and B0034[4] for tunning for expression level of reporter gene sfGFP. K1031803 consists of Pu promoter, RBS B0031 and reporter gene sfGFP (Fig 2a). Induction ratio was calculated from fluorescence intensity, showing the performance of K1031803(Fig 2b)

Fig 2 Construction and tunning of reporter circuit Pu-B0031-sfGFP (a) The orange arrow represents Pu promoter for XylR. The green oval stands for RBS B0031. sfGFP coding sequence is shown with dark blue, while terminator B0015[5] is in dark red. (b) Horizontal axis represents biosensor circuit J23114-XylR adopting different RBS. Vertical axis stands for induction ratio. The dashed box refers to data for reporter circuit Pu-B0031-sfGFP in collocation with biosensor circuit J23114-XylR.
