Amyloid Fibrils

Amyloid Fibrils

Amyloid fibrils are aggregates of misfolded proteins. Under most circumstances, misfolded proteins are either refolded by chaperone proteins or degraded by the proteasome. However, in the case of a mutation or a disease, these proteins can accumulate to form large clusters and often further assemble to form elongated fibers, called fibrils.
Amyloid deposits were observed as early as 1639 in the liver and the spleen. In 1854, Rudolph Virchow performed iodine staining,...

Protein Folding

Protein Folding

Proteins are chains of amino acids linked together by peptide bonds. Upon synthesis, a protein folds into a three-dimensional conformation, critical to its biological function. Interactions between its constituent amino acids guide protein folding, and hence the protein structure is primarily dependent on its amino acid sequence.
Protein Structure Is Critical to Its Biological Function
Proteins perform a wide range of biological functions such as catalyzing chemical reactions, providing...

Multi-pass Transmembrane Proteins and β-barrels

Multi-pass Transmembrane Proteins and β-barrels

In multi-pass transmembrane proteins, the polypeptide chain crosses the membrane more than once. The transmembrane polypeptide chain either forms an α-helix or β-strand structure. α-Helix containing multi-pass transmembrane proteins are ubiquitous, whereas β-strand containing ones are mainly found in gram-negative bacteria, mitochondria, and chloroplasts.

Area of Science:

Supramolecular chemistry
Materials science
Peptide self-assembly

Background:

Amphiphilic peptides are building blocks for self-assembled nanostructures.
Naphthalene diimide (NDI) moieties are known for their electronic properties and π-stacking capabilities.

Purpose of the Study:

To create peptide-based fibrils with controllable intermolecular interactions.
To explore the potential of these materials for self-synthesizing applications.

Main Methods:

Synthesizing short amphiphilic peptides with NDI side chains.
Characterizing the self-assembled fibril structures and their π-stacking interactions.

Main Results:

The synthesized peptides self-assemble into fibrils.
Substantial intermolecular π-stacking interactions were observed within the fibrils.
These π-stacking interactions could be manipulated without altering the overall fibril structure.

Conclusions:

Peptide-NDI conjugates offer a route to self-assembled materials with tunable electronic interactions.
This system represents a foundational step toward developing functional self-synthesizing materials.
