Studying the Competence Regulon Quorum Sensing Circuity in Streptococcus mitis
… factor production, biofilm formation, and competence development bacteria rely on the production and release of signaling molecules into their environment. QS could thus be utilized as a potential non-antibiotic therapeutic strategy to control infections without affecting the survival of …

The contribution of competence system to the virulence of Streptococcus pneumoniae
Competence induction in Streptococcus pneumoniae (pneumococcus) is initiated by the binding of the 17-amino acid competence stimulating peptide (CSP) to its membrane-associated histidine sensor kinase ComD. ComD autophosphorylates and subsequently phosphorylates and activates its cognate response …

Quorum Sensing and Virulence Regulation in Commensal and Pathogenic Bacteria
… regulates collective behaviors including genetic competence, biofilm formation, virulence, and horizontal gene transfer. In streptococci, QS commonly occurs through the ComABCDE and ComRS signaling pathways, which coordinate transcriptional responses through competence-associated regulators such …

Structure–Activity Analysis of Peptide-Mediated Quorum Sensing in Streptococcus mitis
… formation, and resistance acquirement through competence without directly killing the bacteria. In this study we examined QS modulation in Streptococcus mitis, a commensal oral bacterium that has recently been identified as an opportunistic pathogen capable of causing serious infections in …

Molecular investigation of competence development by streptococcus pneumoniae during in vivo infection
Submission published under a 24 month embargo labeled 'Closed Access', the embargo will last until 2026-05-01

Molecular dissection of competence regulated virulence in Streptococcus pneumoniae
… to improving genome plasticity, a natural competence system directly contributes to pneumococcal virulence during pneumonia and bacteremia, independent of DNA uptake. Competence is activated when the competence stimulating peptide (CSP), encoded by the comC gene, is processed and exported …
