Doc-SsrA
Doc is a protein usually used in bacteria toxin-antitoxin system (TA system). This TA system is derived from the bacteriophage P1, which lysogenizes in Escherichia coli cells as a stable low-copy plasmid. Doc plays a role of toxin. SsrA is a degradation tag of 11-residue carboxy-terminal peptide tail to the incomplete nascent chain. Doc-SsrA is a part connects Doc and SsrA with TEV site. When there is no TEV in the cell, toxin protein will be degraded; after TEV is produced, it can function normally. In our biosafety switch, this design will reduce the loss of plasmid due to the leaky expression, thus reducing the escape rate.
