AbiZ

Contributors: Florian Tesson

Description

AbiZ was discovered in 2006 on a Lactococcus lactis conjugative plasmid pTR2030 (N/A) .

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

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 (N/A, N/A) .

Example of genomic structure

The AbiZ is composed of 1 protein: AbiZ.

Here is an example found in the RefSeq database:

The AbiZ system in Fusobacterium pseudoperiodonticum (GCF_002763695.1, NZ_CP024700) is composed of 1 protein: AbiZ (WP_099987858.1)

Distribution of the system among prokaryotes

Among the NaN complete genomes of RefSeq, the AbiZ is detected in NaN genomes (NaN %). The system was detected in NaN different species.
