 # AbiJ
+
+## Description
+
+AbiJ was discovered in 1997 on a *Lactococcus lactis* biovar. diacetylactis  :ref{doi=10.1111/j.1574-6968.1997.tb10185.x}.
+
+AbiJ 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}. AbiJ is classified as abortive infection in :ref{doi=10.1016/j.mib.2023.102312}.
+
+AbiJ is composed of one protein AbiJ. AbiJ has some homology with [AbiC](/defense-systems/abic) (PF14355).
+
+## Molecular mechanism
