Widespread in bacteria and archaea, Toxin-antitoxin (TA) systems have been recently demonstrated to function in phage defense. Here we characterize the anti-phage function of a type IV TA system, ShosTA. Using structural and biochemical approaches, we show that ShosT couples phosphoribosyltransferas...

Salmonella Typhimurium establishes systemic infection by replicating in host macrophages. Here we show that macrophages infected with S. Typhimurium exhibit upregulated glycolysis and decreased serine synthesis, leading to accumulation of glycolytic intermediates. The effects on...

To elucidate that ShosTA exerts an anti-phage function, we further explored the interacting proteins of ShosA. IP-MS/MS analysis reveals in vivo interactions between ShosA and some recombination-associated proteins. FLAG-tagged ShosA in the context of the full ShosTA system or FLAG-tag alone are use...
