Seventy-six-megahertz solid-state 13C CPMAS spectra of the SHaPrP(89–143) peptide, acquired at a spinning speed of 10 kHz. (A) Spectrum of the wt SHaPrP(89–143) peptide dried from water. (B) Spectrum of the mutant SHaPrP(89–143, 3AV) peptide dried from water. (C) Spectrum of mutant SHaPrP(89–143, 3AV) peptide after conversion to an aggregated form by precipitation from acetonitrile/water. The lines superimposed over the resonances for V114, A119, and A132 mark the β-sheet chemical shifts.
