Common NameMutacin
DescriptionMutacin is a lantibiotic, a class of peptide antibiotics characterized by the presence of unusual amino acids and a unique post-translational modification involving lanthionine bridges. The chemical structure of mutacins features a cyclic peptide backbone that contributes to their stability and bioactivity. In the context of Streptococcus mutans, the MutRS quorum-sensing system plays a critical role in regulating the production of mutacins, which are potent antimicrobial agents effective against a broad spectrum of pathogens (PMID:39946531 ). The activation of the MutRS system occurs through a short peptide pheromone known as Mutacin Stimulating Peptide, which triggers the synthesis of multiple lantibiotic mutacins across different strains of S. mutans (PMID:39946531 ). These mutacins are implicated in the virulence of S. mutans, contributing to oro-dental diseases and are frequently found in patients with oral potentially malignant disorders (OPMDs) (PMID:39246897 ). The frequency of mutacin gene types in clinical samples has been assessed using polymerase chain reaction (PCR), revealing expression in patients with OPMDs while absent in healthy individuals without caries (PMID:39246897 ).
