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.

Fig.1 ccdA with C-Terminal 6x His-Tag.

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. We flanked each component with a purification tag to observe their expression levels.
