Common NameEnterocin A
DescriptionEnterocin A is a class II bacteriocin, a type of antimicrobial peptide derived from Enterococcus faecium. Its synthesis involves a complete genetic cassette that encodes the mature form of enterocin A, which can be expressed in various host systems, including Escherichia coli and Saccharomyces cerevisiae. In E. coli, optimized expression conditions lead to the production of recombinant leaderless enterocin A, primarily as inclusion bodies, which can be purified for further study. Enterocin A exhibits potent antimicrobial activity, particularly against multidrug-resistant pathogens such as Staphylococcus aureus subsp. Its structure includes two disulphide bonds, which are critical for its biological activity, although the native operon lacks genes for accessory proteins that typically assist in disulphide bond formation. This characteristic highlights the unique pathway of enterocin A's biosynthesis and its potential applications in combating antibiotic resistance. The ability to express enterocin A in yeast also opens avenues for large-scale production, making it a valuable candidate for further research in antimicrobial applications (PMID:40936353 , PMID:40884739 ).
