Comments [?]

case <OC:Staphylococcus>
Function Essential for the production of a quorum sensing system signal molecule, the autoinducing peptide (AIP). This quorum sensing system is responsible for the regulation of the expression of virulence factor genes. Involved in the proteolytic processing of AgrD, the precursor of AIP.
end case
case not <OC:Staphylococcus>
Function May be involved in the proteolytic processing of a quorum sensing system signal molecule precursor.
end case
Subcellular location Cell membrane; Multi-pass membrane protein.
Similarity Belongs to the AgrB family.
