Amyloid structure: conformational diversity and consequences.

ABSTRACT: Many, perhaps most, proteins, are capable of forming self-propagating, β-sheet (amyloid) aggregates. Amyloid-like aggregates are found in a wide range of diseases and underlie prion-based inheritance. Despite intense interest in amyloids, structural details have only recently begun to be revealed as advances in biophysical approaches, such as hydrogen-deuterium exchange, X-ray crystallography, solid-state nuclear magnetic resonance (SSNMR), and cryoelectron microscopy (cryoEM), have enabled high-resolution insights into their molecular organization. Initial studies found that despite the highly divergent primary structure of different amyloid-forming proteins, amyloids from different sources share many structural similarities. With higher-resolution information, however, it has become clea
