Un système de régulation de type quorum sensing de Streptococcus thermophilus actif en milieu solide et en matrice laitière

Archive ouverte | Soille, Séverine | CCSD

International audience. Contexte : Streptococcus thermophilus possède des systèmes de régulation de type quorum sensing qui fonctionnent avec des petits peptides hydrophobes (SHP) jouant le rôle de phéromone et des ...

Rgg-associated SHP signaling peptides mediate cross-talk in Streptococci

Archive ouverte | Fleuchot, Betty | CCSD

We described a quorum-sensing mechanism in the streptococci genus involving a short hydrophobic peptide (SHP), which acts as a pheromone, and a transcriptional regulator belonging to the Rgg family. The shp/rgg genes, found in nea...

Identification of Hanks-Type Kinase PknB-Specific Targets in the Streptococcus thermophilus Phosphoproteome

Archive ouverte | Henry, Celine | CCSD

International audience. Protein phosphorylation especially on serine/threonine/tyrosine residues are frequent in many bacteria. This post-translational modification has been associated with pathogenicity and virulen...
