Enterocin X, composed of two antibacterial peptides (Xα and Xβ), is a novel class IIb bacteriocin fromEnterococcus faecium KU-B5. When combined, Xα and Xβ display variably enhanced or reduced antibacterial activity toward a panel of indicators compared to each peptide individually. InE. faecium strains that produce enterocins A and B, such as KU-B5, only one additional bacteriocin had previously been known.
