Toxin SymE, type I toxin-antitoxin system SymE (SOS-induced yjiW gene with similarity to MazE ) is an SOS-induced toxin. It inhibits cell growth, decreases protein synthesis and increases RNA degradation. It may play a role in the recycling of RNAs damaged under SOS response-inducing conditions. It is predicted to have an AbrB fold, similar to that of the antitoxin MazE. Its translation is repressed by the antisense RNA SymR, which acts as an antitoxin. |
