CcdA-6xHis Antitoxin

BBa_K4137000 codes for the CcdA protein, a component of the CcdA-CcdB toxin-antitoxin system. CcdA binds with CcdB which inhibits CcdB from targeting DNA gyrase thus preventing DNA double-strand breaks.

Characterization

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 cut at EcoRI and SpeI for both the insert and the vector. We flanked each component with a purification tag to observe their expression levels.
