AB - Fibrils from the Parkinson's-disease-related A53T mutant of alpha-synuclein were investigated by solid-state NMR spectroscopy, electron microscopy, and atomic force microscopy. Sequential solid-state NMR resonance assignments were obtained for a large fraction of the fibril core. Experiments conducted above and below the freezing point suggest that the fibrils contain regions with increased mobility and structural elements different from beta-strand character, in addition to the rigid beta-sheet-rich core region. As in earlier studies on wild-type alpha-synuclein, the C-terminus was found to be flexible and unfolded, whereas the main core region was highly rigid and rich in beta-sheets. Compared to fibrils from wild-type alpha-synuclein, the well-ordered beta-sheet region extends to at least L38 and L100. These results demonstrate that a disease-related mutant of alpha-synuclein differs in both aggregation kinetics and fibril structure.
