AbiJ

Contributors: Florian Tesson

Description

AbiJ was discovered in 1997 on a Lactococcus lactis biovar. diacetylactis () .

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

AbiJ is composed of one protein AbiJ. AbiJ has some homology with AbiC (PF14355).

Molecular mechanism

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

Example of genomic structure

The AbiJ is composed of 1 protein: AbiJ.

Here is an example found in the RefSeq database:
