General description

Chemical structure: peptide

Biochem/physiol Actions

This is an endogenous antibiotic peptide and monocyte chemotactic peptide produced by human neutrophils. Defensins are a family of 3-4 kDa (29-34 amino acids) peptides found in the granules of mammalian phagocytes. The members of this famuly are variably arginine-rich and all share 6 conserved cysteine residues that participate in intramolecular disulfide bonds.

Defensins comprise a structural class of small cationic peptides that exert broad-spectrum antimicrobial activities through membrane permeabilization. Their predominantly beta-sheet structure, stabilized by three disulfide bonds, distinguishes them from other antimicrobial peptides which typically form amphiphilic helices. Defensins bind to

A broad-spectrum antimicrobial peptide present in guinea pig neutrophils was isolated, characterized biochemically, and assessed for microbicidal range and potency in vitro. The guinea pig neutrophil peptide (GPNP) was purified to homogeneity from a granule-rich subcellular fraction of peritoneal exudate
