CcdA coding sequence + Myc Tag
The above sequence encodes for the CcdA protein, a antitoxin formany bacteria including Escherichia coli. By forming CcdA-CcdB complex by binding with CcdB, CcdB loses its ability to interact with DNA gyrase thus losing its toxicity. The Myc tag is a polypeptide protein tag added for protein purification and identification, which serves similar functions as the 6xHis tag.
Construct Design
We obtained the sequence for ccdA from IDT through gblock synthesis. Since we aimed to develop determine how different combinations of our toxin-antitoxin system components (ccdA, ccdB, mleR) affect one another's activity to verify our kill switch theory, we designed our constructs with biobrick restriction sites that bracket our genetic components--to insert one of our components into our backbone pSB1C3, we would cut at EcoRI and SpeI for both the insert and the vector. We also flanked each component with a purification tag to observe their expression levels.
