+## Description
+ApeA is defense system composed of one protein, initially described as a member of the HEPN superfamily which groups proteins with nucleotide binding activity ([CL0291](https://www.ebi.ac.uk/interpro/set/pfam/CL0291/)). 
+
+ApeA is predicted to act *via* an abortive infection mechanism.
+
+## Molecular mechanism
