Common NameLactococcin mmfii
DescriptionLactococcin mmfii is a novel class IIa bacteriocin produced by Lactococcus lactis MMFII, isolated from a Tunisian dairy product. This peptide falls within the chemical class of bacteriocins, which are ribosomally synthesized antimicrobial peptides. The chemical structure of lactococcin mmfii features a characteristic N-terminal YGNGV consensus motif, contributing to its bioactivity, particularly against Listeria species. In the context of its biological pathways, lactococcin mmfii interacts with key CRC-associated proteins such as COX-2, CASP9, PI3K, and IL18R, indicating its potential role in modulating cellular processes related to inflammation and cancer (PMID:35711771 ). Additionally, it has been identified as a promising therapeutic candidate for inhibiting the Omicron variant of SARS-CoV-2, alongside other bacteriocins like Salivaricin B and Pediocin PA-1 (PMID:36591650 ). The unique properties of lactococcin mmfii highlight its importance in both food microbiology and potential therapeutic applications, underscoring the relevance of bacteriocins in contemporary biomedical research (PMID:11728715 ).
