CRYSTAL STRUCTURE OF DEFENSIN HNP-3, AN AMPHIPHILIC DIMER: MECHANISMS OF MEMBRANE PERMEABILIZATION
Contents |
Overview
Defensins (molecular weight 3500 to 4000) act in the mammalian immune response by permeabilizing the plasma membranes of a broad spectrum of target organisms, including bacteria, fungi, and enveloped viruses. The high-resolution crystal structure of defensin HNP-3 (1.9 angstrom resolution, R factor 0.19) reveals a dimeric beta sheet that has an architecture very different from other lytic peptides. The dimeric assembly suggests mechanisms by which defensins might bind to and permeabilize the lipid bilayer.
Disease
Known disease associated with this structure: Mental retardation, X-linked, South African type OMIM:[300243]
