Classification system for bacteriocins [92].

Classes	Characteristics
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
