 # AbiV
+
+## Description
+AbiV was discovered was discovered in 2008 in *Lactococcus lactis* ref:{doi=10.1023/A:1002027321171}.
+
+AbiO is one of the so-called "Abi" systems for "Abortive infection" discovered in the 90's in research related to the dairy industry :ref{doi=10.1016/j.mib.2005.06.006}. Even though their name corresponds to an abortive infection, their mechanism of action does not necessarily correspond to an abortive infection. AbiV system is classified as an abortive infection in :ref{doi=10.1016/j.mib.2023.102312}
+
+This system is composed of one single protein containing a HEPN domain (HEPN_AbiV PF18728).
+
+## Molecular mechanism
+As far as we are aware, the molecular mechanism is unknown. 
+
 ## Example of genomic structure
 
 The AbiV is composed of 1 protein: AbiV.
