 # AbiZ
+
+## Description
+
+AbiZ was discovered in 2006 on a *Lactococcus lactis* conjugative plasmid pTR2030 :ref{doi=10.1128/JB.00904-06}.
+
+AbiZ 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}. AbiZ is classified as abortive infection in :ref{doi=10.1016/j.mib.2023.102312}.
+
+AbiZ is composed of a single protein AbiZ.
+
+## Molecular mechanism
+AbiZ acts as an abortive infection system. AbiZ proteins sense holins and lysins from the infecting bacteriophage and use them to induce premature cell lysis :ref{doi=10.1128/JB.00904-06,10.1146/annurev-virology-011620-040628}.  
+
 ## Example of genomic structure
 
 The AbiZ is composed of 1 protein: AbiZ.
