 # SanaTA
+
+## Description
+
+The SanaTA system is composed of 2 proteins: SanaT and, SanaA, where SanaT encodes a toxin and SanaA encodes an antitoxin to form a toxin-antitoxin (TA) system. The toxin protein, SanaT, contains a Nucleotidyl transferase domain (PF08843). This system provides resistance against mutated T7 phages that lack the nonessential 4.5 gene in *Shewanella sp.* ANA-3. Sberro et al. showed that the defensiveness of sanaTA depends on the cleavage of SanaA by the Lon system, a protease that degrades the antitoxin to allow the activity of the toxin :ref{doi=10.1016/j.molcel.2013.02.002}.
+
+## Molecular mechanism
+
+It has been shown to function as a toxin-antitoxin (TA) system.
