CC   -!- FUNCTION: Plays a role in the bacteriolysis. Is activated under
CC       conditions of high osmolarity by the factor sigma S. Entericidin A
CC       functions as an antidote.
CC   -!- SUBCELLULAR LOCATION: Cell membrane; Lipid-anchor.
CC   -!- SIMILARITY: Belongs to the EcnA/EcnB lipoprotein family. {ECO:0000305}.
