For detailed information concerning XylS, please visit 2013 Peking iGEM Biosensor XylS


Characterization

In order to fine-tune the performance of XylS biosensor, we constructed a library of Pc constitutive promoters at different intensity. BBa_K1031913 is composed of three elements, the constitutive Pc promoter J23109, coding sequence of XylS and terminator B0015. (Fig 1)

Data shown

Induction ratio of XylS biosensor library from ON/OFF test that utilizes different Pc promoters to control the expression of XylS. The dashed box refers to data for Pm/J23109-XylS biosensor circuit. (Fig 2)

Fig 2 Horizontal axis stands for different XylS biosensor with Pc promoters of different strength. The expression strength of these constitutive promoters, J23113, J23109, J23114, J23105, J23106 is 21, 106, 256, 623, and 1185, respectively, according to the Parts'registry. Four kinds of aromatics, namely BzO, 2-MxeBzO, 3-MeBzO and 4-MeBzO, shown with different color intensities, were tested following Test Protocol 1. Vertical axis represents the ON/OFF induction ratio. The dashed box refers to performance of Pm/J23109-XylS biosensor circuit.
