Atomic-resolution structure of a doublet cross-beta amyloid fibrilAtomic-resolution structure of a doublet cross-beta amyloid fibril

Function[TTHY_RAT] Thyroid hormone-binding protein. Probably transports thyroxine from the bloodstream to the brain.[1] Publication Abstract from PubMedThe cross-beta amyloid form of peptides and proteins represents an archetypal and widely accessible structure consisting of ordered arrays of beta-sheet filaments. These complex aggregates have remarkable chemical and physical properties, and the conversion of normally soluble functional forms of proteins into amyloid structures is linked to many debilitating human diseases, including several common forms of age-related dementia. Despite their importance, however, cross-beta amyloid fibrils have proved to be recalcitrant to detailed structural analysis. By combining structural constraints from a series of experimental techniques spanning five orders of magnitude in length scale--including magic angle spinning nuclear magnetic resonance spectroscopy, X-ray fiber diffraction, cryoelectron microscopy, scanning transmission electron microscopy, and atomic force microscopy--we report the atomic-resolution (0.5 A) structures of three amyloid polymorphs formed by an 11-residue peptide. These structures reveal the details of the packing interactions by which the constituent beta-strands are assembled hierarchically into protofilaments, filaments, and mature fibrils.
