AbiE was discovered in 1995 on a Lactococcal plasmid :ref{doi=10.1128/aem.61.12.4321-4328.1995} together with [AbiF](/defense-systems/abif).
AbiE was discovered in 1995 on a Lactococcal plasmid :ref{doi=10.1128/aem.61.12.4321-4328.1995} together with AbiF a homolog of [AbiD](/defense-systems/abid)](/defense-systems/abid).
AbiE 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}. AbiE is classified as abortive infection in :ref{doi=10.1016/j.mib.2023.102312}.
