Self-assembling amphiphilic peptides†
The self-assembly of several classes of amphiphilic peptides is reviewed, and selected applications are discussed. We discuss recent work on the self-assembly of lipopeptides, surfactant-like peptides and amyloid peptides derived from the amyloid-β peptide. The influence of environmental variables such as pH and temperature on aggregate nanostructure is discussed. Enzyme-induced remodelling due...
متن کاملStructures, function and applications of amphiphilic peptides
Major recent ad ances: Amphiphilic peptides, in other words, peptides that contain hydrophobic and hydrophilic regions along their lengths, have been molecularly designed and exploited in various ways. Most notable advancements in the past few years are their proposed use for scaffolds for nanometer structures such as molecular wires and mineralization of hydroxyapatite crystals in a particular...
متن کاملPEG-stabilized lipid disks as carriers for amphiphilic antimicrobial peptides.
Antimicrobial peptides hold potential as a possible alternative, or complement, to conventional antibiotics but new, safe and efficient means are needed for formulation and administration of the peptides. In this study we have investigated the utility of a novel type of lipid particles, the polyethylene glycol-stabilized lipid disks, as carriers for the model peptide melittin. The structural in...
متن کاملMembrane disruption ability of facially amphiphilic helical peptides.
A helical 14-residue peptide containing four polar, but uncharged, benzo-21-crown-7 side-chains aligned along one face induces significantly more vesicle leakage than analogous 21-mer or 7-mer peptides.
متن کاملElasticity of Lipid Bilayer Interacting with Amphiphilic Helical Peptides
Amphiphilic helical peptides exhibit an insertion transition when they interact with lipid bilayers. At low concentrations, the peptides adsorb at the hydrophilic-hydrophobic interface with the helical axes parallel to the bilayer surface. However, if the peptide concentration is above a critical value, a macroscopic fraction of the peptide molecules insert perpendicularly into the bilayer. The...
