A novel target-specific, salt-resistant antimicrobial peptide against the cariogenic pathogen Streptococcus mutans
In this study, we constructed and evaluated a target-specific, salt-resistant antimicrobial peptide (AMP) that selectively targeted Streptococcus mutans, a leading cariogenic pathogen. The rationale for creating such a ... -
The BceABRS four-component system regulates the bacitracin-induced cell envelope stress response in Streptococcus mutans
Streptococcus mutans is known to be resistant to bacitracin, a cyclic polypeptide antibiotic produced by certain species of the genus Bacillus. This property is often exploited in the isolation of S. mutans strains from ... -
Quorum sensing and bacterial social interactions in biofilms
Many bacteria are known to regulate their cooperative activities and physiological processes through a mechanism called quorum sensing (QS), in which bacterial cells communicate with each other by releasing, sensing and ... -
Structure-activity analysis of quorum-sensing signaling peptides from Streptococcus mutans
Streptococcus mutans secretes and utilizes a 21-amino-acid signaling peptide pheromone to initiate quorum sensing for genetic competence, biofilm formation, stress responses, and bacteriocin production. In this study, we ... -
Detachment of Streptococcus mutans biofilm cells by an endogenous enzymatic activity
Previous studies have shown that Streptococcus mutans NG8 possesses an endogenous surface protein-releasing enzyme (SPRE) activity that liberates its own surface proteins (S. P. Lee, Infect. Immun. 60:4032-4039, 1992). The ...
