Three peptides with antibacterial activity toward enterotoxigenic Escherichia coli have been purified from a pepsin digest of bovine lactoferrin. All peptides were cationic and originated from the N-terminus of the molecule in a region where a bactericidal peptide, lactoferricin B, had been previously identified. The most potent peptide, peptide I, was almost identical to lactoferricin B; the sequence corresponded to residues 17 to 42, and the molecular mass was 3195 as determined by mass… CONTINUE READING
