Toxin-antitoxin (TA) systems have been reported in the genomes of most bacterial species, and their role when located on the chromosome is still debated. TA systems are particularly abundant in the massive cassette arrays associated with chromosomal superintegrons (SI). Here, we describe the characterization of two superintegron cassettes encoding putative TA systems. The first is the phd-doc(S...
Antibiotic resistance and microorganism virulence have been consistently exhibited by bacteria and archaea, which survive in conditions of environmental stress through toxin-antitoxin (TA) systems. The HP0892-HP0893 TA system is one of the two known TA systems belonging to Helicobacter pylori. The antitoxin, HP0893, binds and inhibits the HP0892 toxin and regulates the transcription of the TA o...
Bacterial toxin-antitoxin (TA) systems typically consist of a small, labile antitoxin that inactivates a specific longer-lived toxin. In Escherichia coli, such antitoxins are proteolytically regulated by the ATP-dependent proteases Lon and ClpP. Under normal conditions, antitoxin synthesis is sufficient to replace this loss from proteolysis, and the bacterium remains protected from the toxin. H...
Structurally nanoengineered antimicrobial peptide polymers (SNAPPs) are an emerging class of antimicrobials against multidrug-resistant bacteria. Their encapsulation in particle carriers can improve their therapeutic efficacy by preventing degradation, reducing clearance, and enhancing intracellular delivery dosage to bacteria-infected host cells. Herein, two template-mediated strategies report...
