Toxin/antitoxin (TA) systems are present in nearly every prokaryotic genome and play the important physiological roles of phage inhibition by reducing metabolism (this includes …
Host–pathogen conflicts are crucibles of molecular innovation,. Selection for immunity to pathogens has driven the evolution of sophisticated immunity mechanisms throughout …
Translation-targeting toxic small alarmone synthetases (toxSAS) are effectors of bacterial toxin-antitoxin systems that pyrophosphorylate the 3′-CCA end of transfer RNA (tRNA) to …
Anti-phage defenses must rapidly sense and respond to diverse viruses. A recent pair of papers in Nature reveal via structural and functional assays how the PARIS defense system …
