A multi-timescale analysis of the backbone dynamics of HET-s (218â??289) fibrils is described based on multiple site-specific R 1 and R 1Ï? data sets and S 2 measurements via REDOR for most backbone 15N and 13Cα nuclei. 15N and 13Cα data are fitted with motions at three timescales. Slow motion is found, indicating a global fibril motion. We further investigate the effect of 13Câ??13C transfer in measurement of 13Cα R 1. Finally, we show that it is necessary to go beyond the Redfield approximation for slow motions in order to obtain accurate numerical values for R 1Ï?.

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...

Solid-state NMR, electrophysiology and molecular dynamics characterization of human VDAC2
Abstract
The voltage-dependent anion channel (VDAC) is the most abundant protein of the outer mitochondrial membrane and constitutes the major pathway for the transport of ADP, ATP, and other metabolites. In this multidisciplinary study we combined solid-state NMR, electrophysiology, and molecular dynamics simulations, to study the structure of the human VDAC isoform 2 in a lipid bilayer environment. We find that the structure of hVDAC2 is similar to the...

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...
