Description

AbiN was discovered in Lactococcus lactis subsp. cremoris S114 in 1998 () .

AbiN is one of the so-called "Abi" systems for "Abortive infection" discovered in the 90's in research related to the dairy industry () . AbiN is classified as unknown for abortive infection phenotype in () .

AbiN is a single gene system composed of the protein AbiN.

Molecular mechanism

As far as we are aware, the molecular mechanism is unknown.

Example of genomic structure

The AbiN is composed of 1 protein: AbiN.

Here is an example found in the RefSeq database:
