Description
This is a construct composed of a dually-repressed promoter, an RBS of medium strength, the reporter protein RFP, and a single, well-characterized terminator. The promoter is repressed in the presence of TetR and/or p22 cII, and ideally allows no expression of the reporter RFP. The RFP used is BioBrick part J06504, a monomeric RFP which has been optimized for bacteria.
The presence of RFP makes this construct a useful reporter in E.coli systems in which expression levels of either TetR and/or p22 cII need to be examined.
Notes
During the design of this part, the majority of design considerations were dealt with during the construction of the TetR/p22 cII dually repressed promoter (K101002). The promoter design required careful consideration of which operator sites to include, as well as which -35 and -10 sites should be utilized.
A medium strength RBS was chosen to increase the ribosome binding affinity to an appropriate level. Additionally, the decision was made to use only a single, well-characterized terminator, rather than a double terminator.
