Protein and Protein Structure

Protein and Protein Structure

Proteins are one of the most abundant organic molecules in living systems and have the most diverse range of functions of all macromolecules. Proteins may be structural, regulatory, contractile, or protective. They may serve in transport, storage, or membranes; or they may be toxins or enzymes. Their structures, like their functions, vary greatly. They are all, however, amino acid polymers arranged in a linear sequence.
A protein's shape is critical to its function. For example, an enzyme...

Molecular Chaperones and Protein Folding

Molecular Chaperones and Protein Folding

The native conformation of a protein is formed by interactions between the side chains of its constituent amino acids. When the amino acids cannot form these interactions, the protein cannot fold by itself and needs chaperones. Notably, chaperones do not relay any additional information required for the folding of polypeptides; the native conformation of a protein is determined solely by its amino acid sequence. Chaperones catalyze protein folding without being a part of the folded protein.
The...

Conservation of Protein Domains Over Different Proteins

Conservation of Protein Domains Over Different Proteins

Protein domains are small structurally independent units that are part of a single amino acid chain. Although these domains are often structurally independent, they may rely on synergistic effects to perform their functions as part of a larger protein. Protein domains may be conserved within the same organism, as well as across different organisms.
A limited set of protein domains often duplicate and recombine during evolution. These domains can be organized in different combinations to...

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,...

Background:

Abiotic aromatic foldamer sequences can form helix-turn-helix motifs in organic solvents.
Designing abiotic molecules with predictable self-assembly is crucial for creating novel architectures.

Purpose of the Study:

To design and synthesize a novel abiotic foldamer sequence capable of forming a stable trimeric quaternary structure.
To investigate the self-assembly behavior of this foldamer in solution.

Main Methods:

Computational design of a foldamer motif with enhanced hydrogen bonding capabilities.
Synthesis of the designed foldamer sequence.
Characterization of self-assembly using Nuclear Magnetic Resonance (NMR), Circular Dichroism (CD), and Molecular Dynamics (MD) simulations.

Main Results:

Evidence for two stable, discrete aggregates: a designed trimer and a water-inclusive dimer.
The equilibrium between the trimer and dimer is sensitive to changes in water content and temperature.
Successful design and synthesis of a foldamer with controllable self-assembly.

Conclusions:

Demonstrated the successful design of an abiotic foldamer that self-assembles into defined quaternary structures.
Highlighted the potential for controlling abiotic architectures through environmental factors like water content and temperature.
These findings represent significant progress in the development of protein-like abiotic architectures.
