 # ShosTA
+
+## Description
+
+ShosTA system was first described as a Toxin/Antitoxin system in 2012 :ref{doi=10.1101/gr.133850.111} without demonstration of antiphage activity. In 2022, a paper described the same system as "DprA + PRTase" inside P2 like prophages and prooves its antiphage activity. Finally, the antiphage activity was also prooved in another study with the original name ShosTA :ref{doi=10.1016/j.chom.2022.09.017}.
+
+This system is composed of two protein: ShosT and ShosA encoding for Hydrolase/PRTase and DprA (nucleotid binding) respectively.
+
+## Molecular mechanism
+The ShosTA system is a toxin (ShosT) antitoxin (ShosA) system. The domains of ShosT (Hydrolase and PRTase) allows us to hypothesize a toxicity linked to host protein degradation.
+
 ## Example of genomic structure
 
 The ShosTA system is composed of 2 proteins: ShosA and, ShosT.
