CC   -!- FUNCTION: Essential for the production of a quorum sensing system
CC       signal molecule, the autoinducing peptide (AIP). This quorum sensing
CC       system is responsible for the regulation of the expression of virulence
CC       factor genes. Involved in the proteolytic processing of AgrD, the
CC       precursor of AIP. {ECO:0000255|HAMAP-Rule:MF_00784}.
CC   -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000255|HAMAP-Rule:MF_00784};
CC       Multi-pass membrane protein {ECO:0000255|HAMAP-Rule:MF_00784}.
CC   -!- SIMILARITY: Belongs to the AgrB family. {ECO:0000255|HAMAP-
CC       Rule:MF_00784}.
