An oxygen-sensitive toxin-antitoxin system. Nat Commun. 2016 Dec 8;7:13634.
An artist view of oxygen approaching a channel on the surface of YmoB anttitoxin that reduces Hha to non-toxic levels by activating molecular oxygen. Marimon et al have solved the structure of the antitoxin by NMR and uncovered a new class of toxin-antitoxin system relevant for biofilm formation
