Copper Biosensor

This part constitutively expresses the CueR repressor. This repressor then inhibits the expression of RFP from the downstream PcopA promoter. In the presence of copper, the repression of CueR is inhibited leading to greater RFP expression. Fluorescence of this construct has been shown to increase with increasing copper concentration in both a qualitative and quantitative manner.

Copper detection circuit diagram A: Copper biosensor in the presence of copper ions Copper ions inhibit the binding of CueR to the pCopA promoter, allowing for expression of RFP. B: Copper biosensor in the absence of copper ions In the absence of copper ions, CueR binds to the pCopA promoter and inhibits RFP expression. A reduced amount of RFP is synthesized due to some leaky expression of the RFP gene.
