Table 2: Classification system for bacteriocins [92].

ClassesCharacteristics

Class I Lantibiotics
 Class Ia Small (19–38 amino acids), elongated, positively charged peptides that form pores
 Class Ib Globular peptides that interfere with essential enzymes

Class II Nonlanthionine containing-bacteriocins
 Class IIa Pediocin-like peptides that contain the YGNGVXCXXXXVXV consensus sequence in their N-terminal
 Class IIb Two-peptide bacteriocins, require both peptides for activity
 Class IIc Cyclic peptides, N- and C-terminal of peptides are covalently linked
 Class IId Single non-pediocin like peptides
