Keyword - Quorum sensing (KW-0673)

Definition

Protein involved in quorum sensing (QS). QS is a phenomenon whereby the accumulation of signaling molecules enables a single cell to sense the number of bacteria (cell density). The bacterial reponse to QS includes adaptation to availability of nutrients, defence against other microorganisms which may compete for the same nutrients and the avoidance of toxic compounds potentially dangerous for the bacteria.
