De novo designed peptides for biological applicationsw
In recent years our ability to design and assemble peptide-based materials and objects de novo (i.e. from first principles) has improved considerably. This brings us to a point where the resulting assemblies are quite sophisticated and amenable to engineering in new functions. Whilst such systems could be used in a variety of ways, biological applications are of particular interest because of t...
متن کاملSelf-activation in de novo designed mimics of cell-penetrating peptides.
The unique ability of cell-penetrating peptides (CPPs), also known as protein transduction domains, to navigate across the nonpolar biological membrane has been under intense investigation. In vitro studies have shown that multiple mechanisms are available, with the precise details being dependent on the peptide and cell line studied. The several clearly demonstrated pathways include various fo...
متن کاملShape-specific nanostructured protein mimics from de novo designed chimeric peptides.
Natural proteins self-assemble into highly-ordered nanoscaled architectures to perform specific functions. The intricate functions of proteins have provided great impetus for researchers to develop strategies for designing and engineering synthetic nanostructures as protein mimics. Compared to the success in engineering fibrous protein mimetics, the design of discrete globular protein-like nano...
متن کاملDe novo design of potent antimicrobial peptides.
Lipopolysaccharide (LPS), shed by gram-negative bacteria during infection and antimicrobial therapy, may lead to lethal endotoxic shock syndrome. A rational design strategy based on the presumed mechanism of antibacterial effect was adopted to design cationic antimicrobial peptides capable of binding to LPS through tandemly repeated sequences of alternating cationic and nonpolar residues. The p...
متن کاملDe novo designed protein transduction domain mimics from simple synthetic polymers.
Protein transduction domains (PTDs) that readily transverse cellular membranes are of great interest and are attractive tools for the intracellular delivery of bioactive molecules. Learning to program synthetic polymers and oligomers with the appropriate chemical information to capture adequately the biological activity of proteins is critical to our improved understanding of how these natural ...
