Amyloid fibrils from Alzheimer's amyloid-beta peptides (A?) are found to be polymorphic. So far, 14 A?40 fibril structures have been determined. The mechanism of why one particular protein sequence adopts so many different three-dimensional structures is yet not understood. In this work, we describe the assignment of the NMR chemical shifts of two Alzheimer's disease fibril polymorphs, P1 and P2, which are formed by the amyloid-beta peptide A?40. The assignment is based on ^(13)C-detected 3D...
[NMR paper] Solid-state NMR spectroscopic analysis for structure determination of a zinc-bound catalytic amyloid fibril
Solid-state NMR spectroscopic analysis for structure determination of a zinc-bound catalytic amyloid fibril
Zinc ions are commonly involved in enzyme catalysis and protein structure stabilization, but their coordination geometry of zinc-protein complex is rarely determined. Here, in this chapter, we introduce a systematic solid-state NMR approach to determine the oligomeric assembly and Zn^(2+) coordination geometry of a de novo designed amyloid fibrils that catalyze zinc dependent ester hydrolysis. NMR chemical shifts and intermolecular contacts confirm that the peptide forms...

Abstract
The formation of fibrils of the amyloid-? (A?) peptide is considered to be a key event in the pathology of Alzheimer's disease (AD). The determination of a high-resolution structure of these fibrils is relevant for the understanding of the molecular...

Current interest in amyloid fibrils stems from their involvement in neurodegenerative and other diseases and from their role as an alternative structural state for many peptides and proteins. Solid-state nuclear magnetic resonance (NMR) methods have the unique capability of providing detailed structural constraints for amyloid fibrils, sufficient for the development of full molecular models. In...
