Defensins

Defensins are small, basic proteins with conserved cysteine residues that form disulfide bridges. Being an integral part of the innate immune system, defensins are antimicrobial and active against many bacteria, fungi, and viruses. These peptides are cationic and interact with the membranes of invading microbes, which are negatively charged due to the presence of lipopolysaccharides (LPS) or lipoteichoic acid (LTA). LTA and LPS have higher affinity for the defensins than for Ca+2 and Mg+2 ions. The larger defensin molecule displaces the smaller ion, changing the membrane structure and affecting the stability of the membrane; this can lead to the formation of pores and subsequent depolarization or lysis of the invading cell. Defensins can also contribute to the adaptive immune system through chemotaxis of leukocytes. GoldBio offers high-quality, affordable recombinant defensins for research purposes.
