We present a strategy to solve the high-resolution structure of amyloid fibrils by solid-state NMR and use it to determine the atomic-resolution structure of the prion domain of the fungal prion HET-s in its amyloid form. On the basis of 134 unambiguous distance restraints, we recently showed that HET-s(218-289) in its fibrillar state forms a left-handed β-solenoid, and an atomic-resolution NMR structure of the triangular core was determined from unambiguous restraints only. In this paper, we go considerably further and present a comprehensive protocol using six differently labeled samples, a collection of optimized solid-state NMR experiments, and adapted structure calculation protocols. The high-resolution structure obtained includes the less ordered but biologically important C-terminal part and improves the overall accuracy by including a large number of ambiguous distance restraints.
