Common NameEnterocin EJ97
DescriptionEnterocin EJ97 is a bacteriocin, a class of antimicrobial peptides produced by certain bacteria, specifically Enterococcus faecalis EJ97. This 44-residue-long peptide exhibits significant antimicrobial activity and is part of a broader family of leaderless bacteriocins, which includes enterocin K1 and LsbB (PMID:28515717 ). The structural characterization of enterocin EJ97 has been documented, revealing its natively unfolded nature, which may contribute to its function and interaction with target cells (PMID:20385607 ). The production of enterocin EJ97 is influenced by various substrate compositions, and studies have focused on optimizing conditions for its semi-preparative scale purification (PMID:17901993 ). Additionally, enterocin EJ97 has been shown to interact with specific receptors, such as Eep, facilitating its bactericidal effects (PMID:33679682 ). The presence of enterocin EJ97, along with other bacteriocins and antimicrobial resistance genes, highlights the complex genetic landscape of its producing strains, which may contribute to their virulence and adaptability (PMID:39723131 ). Overall, enterocin EJ97 represents a promising candidate for further research in the development of novel antimicrobial agents.
