CC   -!- FUNCTION: ABI may interact with a target in the cell membrane, which
CC       could be the product of the host's cmrA gene, and cause disruption of
CC       the cellular membrane such that lysis of the infected cell and death of
CC       the infecting phage would result.
CC   -!- SUBCELLULAR LOCATION: Cell membrane. Note=This very hydrophobic protein
CC       could insert itself into membranes.
CC   -!- MISCELLANEOUS: When phage T5 or its close relative BF23, infects cells
CC       harboring a ColIb plasmid, the infection is abortive. The mechanism
CC       involves gene products from the phage, the ColIb plasmid, and the host.
