The pore is completely plugged towards its periplasmic end, though, by the presence of a large 150-residue N-terminal domain, which consists mainly of a four-stranded β-sheet. Two loops from this ...

The study's findings, published in Acta Biomaterialia, illuminate the formation of β-sheet structures within the hydrogel matrix, mimicking the nanostructures of amyloid-β proteins. By culturing ...

X-ray-diffraction analyses on purified fibrils indicated that the constituent proteins were unusually rich in highly ordered, β-pleated sheet structure, providing an apparent explanation for ...
