J23114-HcaR


Characterization

In order to fine-tune the performance of HcaR biosensor, we constructed a library of Pc constitutive promoters at different intensity. BBa_K1031444 is composed of three elements, the constitutive Pc promoter J23114[1], coding sequence of HcaR and terminator B0015[2]. (Fig 1)

Data shown

We constructed a RBS library of different intensity controlling expression of sfGFP in collocation with Ph/J23114-HcaR biosensor circuit. The dashed box refers to data for Ph-B0031/J23114-HcaR biosensor circuit (Fig 2), which obtains the optimal performance comparing with B0032, B0033 and B0034.

Four kinds of aromatics shown with different color intensities, were tested following Test Protocol 1 [1]. Vertical axis represents the ON-OFF induction ratio.
