Scientists have found that short peptides can remain stable and fold into shapes that may give them biological functions in highly acidic conditions similar to Venus's cloud layer. This discovery opens up new possibilities for the search for life on planets that don't resemble Earth.
A team of scientists developed a chlorophyll-based supramolecular polymer that can gradually evolve from nonhelical fibers into well-defined helical structures. The transformation occurs cooperatively and is driven by small energy differences between stable arrangements, offering a blueprint for designing dynamic helical structures.
Researchers at RIKEN successfully spin artificial spider silk that closely matches natural production, mimicking the complex molecular structure of silk. The eco-friendly innovation has potential benefits for environment and biomedical fields.
Researchers have provided new details on structures resulting from 3D domain swapping in antibody light chains, shedding light on mechanisms of protein aggregation. The study suggests that the formation of tetramers may prevent protein aggregation by decreasing flexibility.
Researchers successfully created a periodic rippled beta sheet layer configuration, as predicted by Linus Pauling and Robert Corey in 1953. The new findings enable the rational design of unique materials based on this novel protein structure.
A team of researchers at UC Santa Cruz has created an unusual protein structure known as a ‘rippled beta sheet’ by mixing mirror-image peptides. The study used x-ray crystallography to obtain images of the structure, which closely matches predictions made in 1953 by Linus Pauling and Robert Corey.
Researchers have discovered how methylene blue modifies tau proteins, which aggregate in Alzheimer's disease. The study reveals that methylene blue deactivates molecular residues promoting bonding and acts as a spacer to keep proteins apart, leading to potential treatment strategies.
