Switch-peptides as folding precursors in self-assembling peptides and amyloid fibrillogenesis.
The study of conformational transitions of peptides has obtained considerable attention recently because of their importance as a molecular key event in a variety of degenerative diseases. However, the study of peptide self-assembly into beta-sheets and amyloid beta (Abeta) fibrils is strongly hampered by their difficult synthetic access and low solubility. We have recently developed a new conc...
متن کاملSelf-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 کاملMolecular designer self-assembling peptides.
Chemistry has generally been associated with inorganic and organic syntheses, metal-organic composites, coordinate metal chemistry, catalyses, block copolymer, coating, thin film, industrial surfactants and small-molecule drug development. That is about to change. Chemistry will also expand to the discovery and fabrication of biological and molecular materials with diverse structures, functiona...
متن کاملStimuli-responsive self-assembling peptides made from antibacterial peptides.
How to use bioactive peptide sequences as fundamental building blocks to make hydrogel materials which are stimuli-responsive? In this article, we provide a novel designed peptide comprising two antibacterial peptide sequences (KIGAKI)3-NH2 and a central tetrapeptide linker. Results show that balancing the forces of the electrostatic repulsion of the charged lysine residues against the hydropho...
متن کاملShort self-assembling peptides as building blocks for modern nanodevices.
Short, self-assembling peptides form a variety of stable nanostructures used for the rational design of functional devices. Peptides serve as organic templates for conjugating biorecognition elements, and assembling ordered nanoparticle arrays and hybrid supramolecular structures. We are witnessing the emergence of a new phase of bionanotechnology, particularly towards electronic, photonic and ...
