Amyloid fibrils are insoluble, non-crystalline protein filaments associated with a number of diseases such as Alzheimer’s and Type II diabetes. They can have a functional role in different organisms, and many proteins and peptides have been found to form amyloid fibrils in vitro. This talk will present an overview of what is known regarding their molecular structure, focusing in particular on the fibrils formed by an 11-residue segment from the disease-related protein transthyretin (TTR). This system exemplifies our efforts to characterize the hierarchy of structures present in the fibril form, including the organization of the β-strands into β-sheets (tertiary structure), the β-sheet interface that defines each protofilament (quaternary structure), and the protofilament-to-protofilament contacts that lead to the formation of the complete fibril. Our efforts resulted in the measurement of 110 distance and torsion angle constraints (10 per residue) across all levels of structural organization, resulting in the best resolved amyloid fibril structure so far. The structural investigation benefited extensively from the development of dynamic nuclear polarization, a method used to enhance the sensitivity of MAS NMR experiments, and leading to unprecedented gains in signal-to-noise ratios and acquisition times.
