Default Solid-state NMR sequential assignments of the amyloid core of Sup35pNM.

Solid-state NMR sequential assignments of the amyloid core of Sup35pNM.

Solid-state NMR sequential assignments of the amyloid core of Sup35pNM.

Biomol NMR Assign. 2013 Aug 10;

Authors: Luckgei N, Schütz AK, Habenstein B, Bousset L, Sourigues Y, Melki R, Meier BH, Böckmann A

Abstract
Sup35pNM represents the N-terminal and middle (M) domains of the yeast Saccharomyces cerevisiae prion Sup35p. This fragment is commonly used for structural and functional studies of Sup35p. We here present a solid-state NMR study of fibrils formed by this fragment and show that sequential assignments can be obtained for the rigid and well-ordered parts of the protein using 3D spectroscopy. We describe in detail the sequential assignment of the 22 residues yielding strong, narrow signals with chemical shifts that correspond mostly to ?-sheet secondary-structured amino acids that form the fibril core.

Solid-state NMR analysis of the ?-strand orientation of the protofibrils of amyloid ?-protein
Solid-state NMR analysis of the ?-strand orientation of the protofibrils of amyloid ?-protein 30 November 2012 Publication year: 2012 Source:Biochemical and Biophysical Research Communications, Volume 428, Issue 4</br> </br> Alzheimer’s disease (AD) is caused by abnormal deposition (fibrillation) of a 42-residue amyloid ?-protein (A?42) in the brain. During the process of fibrillation, the A?42 takes the form of protofibrils with strong neurotoxicity, and is thus believed to play a crucial role in the pathogenesis of AD. To elucidate the supramolecular structure of the...

Biomol NMR Assign. 2011 Jul 9; Authors: Gath J, Habenstein B, Bousset L, Melki R, Meier BH, Böckmann A Parkinson's disease is amongst the most frequent and most devastating neurodegenerative diseases. It is tightly associated with the assembly of proteins into high-molecular weight protein species, which propagate between neurons in the central nervous system. The principal protein involved in this process is ?-synuclein which is a...

Solid-state NMR of amyloid membrane interactions.
Solid-state NMR of amyloid membrane interactions. Solid-state NMR of amyloid membrane interactions. Methods Mol Biol. 2011;752:165-77 Authors: Gehman JD, Separovic F Solid-state NMR pulse sequences often feature fewer pulses and delays than the more common solution NMR experiments. This ostensible simplicity, however, belies the care with which experimental parameters must be determined, as solid-state NMR can be much less forgiving of improper experimental set-up. This is especially true of "semi-solid" samples, such as the phospholipid vesicles...

Solid-State NMR Studies of Amyloid Fibril Structure. Solid-State NMR Studies of Amyloid Fibril Structure. Annu Rev Phys Chem. 2010 Apr 2; Authors: Tycko R 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...
