Pre B3 gene
a kill switch strategy. In our Design 1, antitoxin MazE was chosen as the core effector component, with pBad promoter and RNA thermometer acting as sensor components, and the TetR gene and TetR repressible promoter working together as an inverting logic gate. If all goes as expected, MazE will express under 37°C if the medium is free of L-arabinose, but the expression level will drop significantly either with the presence of L-Arabinose or when the ambient temperature is low. To evaluate the behavior of our system, we created three constructs: Firstly, we put all parts together as our plan in Constriuct 1. In Construct 2 , we would like to visualize how MazE will express under different L-Arabinose concentration and ambient temperature for quick check and further assays, so we replaced MazE with RFP. By the same token, we replaced TetR with RFP in Construct 3 to evaluate the expression level of TetR under different concentrations of L-Arabinose in case we needed to troubleshoot the system.
Usage and Biology
The RFP expression of Construct 3 We used RFP(E1010) to monitor the expression of TetR, so that we can figure out how L-arabinose will influence the expression of TetR in our Design 1.
