Part:BBa_K4137014
CcdA regulatory and expression device
The mleR regulatory site which comes from p_mles binds with the RBS and CcdA, the antitoxin that will bind with CcdB when induced by malate acid and detoxifies it, the purification tag 6xHis, and the terminator B1006 (BBa_B1006). This sequence codes for CcdA, the antitoxin which assures chi18h8’s production around the plant roots. The second half contains a T7 promoter, an RBS, a mleR coding complex, a mleR purification tag—6xHis, and a terminator B1006. This half produces and purifies mleR, the regulator of CcdA, which produces when malate acid is present. The construct as a whole code for Ccda is regulated by mleR when malate acid is presented.
Construct Design
We attached a Myc epitope tag downstream of the ccdA sequence for purification purposes. A p_mleS promoter, which induces protein production when malate is present, as well as RBS, are attached upstream to the side of our first open reading frame (ccdA-Myc). A T7 and RBS (AAGGAG) are attached upstream to the side of our open reading frame (mleR-6x his). Terminators BBa_B1006 are attached downstream of each of the open reading frames sequence.
