3G pTlpA

pTlpA promoter BBa_K2500003 flanked by prefix sticky end A and suffix sticky end B in in a 3G-compatible backbone. For more information on 3G hybrid DNA assembly and 3G parts, see the [http://2018.igem.org/Team:William_and_Mary/Part_Collection William and Mary 3G Parts Page].

pTlpA is repressed by TlpA, a heat-sensitive protein which begins to deactivate at 37C. "The TlpA operator is a strong promoter (88-fold stronger than LacI^Q) driven by the transcription factor σ. Interestingly, this promoter has bidirectional activity, with identical thermal regulation in both orientations but approximately 200-fold lower maximal expression in the reverse direction."¹ See pTlpAr BBa_K2680124 for the reverse complement of pTlpA (also in 3G compatible form).
