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

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

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.

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.

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...	nmrlearner	Journal club	0	06-30-2011 01:24 PM
