The signal sequence of yeast killer toxin K2 confers producer self-protection and allows conversion into a modular toxin-antitoxin system
The paper identifies a 49-amino acid signal peptide from the yeast killer toxin K2 that functions as both a secretion signal and a self-protection immunity factor, enabling a modular toxin-antitoxin system.
