pCopA with divergent expressed CueR

Description

To facilitate making any protein under control of a copper-responsive promoter we designed this part. The Biobrick contains the constitutively expressed CueR (transcription factor). On the opposing direction we have the copper sensitive pCopA promoter but with nothing but an RBS inserted downstream of it. The RBS present means that any protein with the ATG biobrick prefix and universal suffix can be inserted with biobrick standard assembly with the correct RBS-ATG distance.

Usage and Biology

The pCopA promoter was initially identified as the promoter of the copper exporting ATPase, CopA. The promoter contains inverted repeats of sequences called CueR boxes with the sequence: CCTTCCNNNNNNGGAAGG. This allows the binding of the DNA binding domains of the copper sensitive transcription factor CueR(1).

CueR is a MerR-type regulator with an interesting mechanism of action whereby it can behave as a net activator or a net repressor under different copper concentrations through interaction with RNA polymerase(1)
