In the 1950s, Linus Pauling and Robert Corey proposed the idea of rippled beta-sheets — sections of proteins— called peptides— that are mirror-images of each other, held together by hydrogen bonds in ...

An unusual protein structure known as a “rippled beta sheet,” first predicted in 1953, has now been created in the laboratory and characterized in detail using x-ray crystallography. The new findings, ...

A newly developed approach can precisely produce four-stranded beta-sheets through metal-peptide coordination, report researchers. Their innovative methodology overcomes long-standing challenges in ...

Scientists have examined the soluble precursor of spider silk and found that a previously undiscovered structural element is key to how the proteins form into the beta-sheet conformation that gives ...

In addition to the natural sequence of amino acids that makes up a protein, their three-dimensional arrangement in space is also critical to their function. For example, β-sheets, which are sheet-like ...
