Antibacterial peptides of bovine lactoferrin: purification and characterization.

Abstract

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 spectrometry. A second, less active peptide, peptide II, consisted of two sequences, residues 1 to 16 and 43 to 48 (molecular mass of 2673), linked by a single disulfide bond. The third peptide, peptide III, also a disulfide-linked heterodimer, corresponded to residues 1 to 48 (molecular mass of 5851), cleaved between residues 42 and 43. Peptides I and II displayed antibacterial activity toward a number of pathogenic and food spoilage microorganisms, and peptide I inhibited the growth of Listeria monocytogenes at concentrations as low as 2 microM. Bacterial growth curves showed that bactericidal effects of peptides I and II were observable within 30 min of exposure. The results confirmed and extended those of earlier studies suggesting that the bactericidal domain of lactoferrin was localized in the N-terminus and did not involve iron-binding sites.

  • Lactoferricin B, having broad spectrum of action including Gram-negative and Gram-positive bacteria, yeasts and filamentous fungi, has been described as the result of hydrolytic action on bovine lactoferrin.

    “An interesting antimicrobial peptide, named Lactoferricin B, having broad spectrum of action including Gram-negative and Gram-positive bacteria, yeasts and filamentous fungi, has been described as the result of the hydrolytic action on bovine lactoferrin (Dionysius and Milne, 1997; Kitts and Weiler, 2003).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
