Common NamePropionicin T1
DescriptionPropionicin T1 is a bacteriocin belonging to the class of antimicrobial peptides produced by certain strains of propionibacteria. This peptide is characterized as a general secretory pathway (sec)-dependent bacteriocin, exhibiting bactericidal activity against all tested propionibacterial species, with the exception of Propionibacterium freudenreichii (PMID:21038096 ). The cloning of the propionicin T1 bacteriocin has been successfully facilitated using the pSL104 vector in Propionibacterium species (PMID:17933941 ). Notably, high-level production of propionicin T1, reaching 640 BU/ml, was achieved in the IFO12426 strain, with the expression plasmid pSL106 being stably maintained in a majority of cells over multiple generations (PMID:17933941 ). In coculture experiments, P. freudenreichii demonstrated propionicin T1 activity, resulting in the death of 90% of sensitive bacteria within 48 hours (PMID:16332788 ). The mature peptide has a molecular weight of 7130.20 Da and shows homology to propionicin T1 (PMID:15109792 ). Studies have indicated a high prevalence of the genes encoding propionicin T1 among classical propionibacteria, with the pctA gene present in 89% of P. thoenii strains, correlating with antimicrobial activity (PMID:15066818 ).
