Multiple and Overlapping Functions of Quorum Sensing Proteins for Cell Specialization in <i>Bacillus</i> Species
Abel Alberto Verdugo-Fuentes, Gabriela Gastélum, Jorge Rocha, Mayra de la Torre
Abstract
In bacterial populations, quorum sensing (QS) systems participate in the regulation of specialization processes and regulate collective behaviors that mediate interactions and allow survival of the species. In Gram-positive bacteria, QS systems of the RRNPP family ( R gg, R ap, N prR, P lcR, and P rgX) consist of intracellular receptors and their cognate signaling peptides. Two of these receptors, Rap and NprR, have regained attention in Bacillus subtilis and the Bacillus cereus group.
