AA amyloidosis is one of the most prevalent forms of systemic amyloidosis and affects both humans and other vertebrates. In this study, we compare MAS solid-state NMR data with a recent cryo-EM study of fibrils involving full-length murine SAA1.1. We address the question whether the specific requirements for the reconstitution of an amyloid fibril structure by cryo-EM can potentially yield a bias towards a particular fibril polymorph. We employ fibril seeds extracted from in to vivo material to...

The conformation of the Congo-red ligand bound to amyloid fibrils HET-s(218â??289): a solid-state NMR study
Abstract
We have previously shown that Congo red (CR) binds site specifically to amyloid fibrils formed by HET-s(218â??289) with the long axis of the CR molecule almost parallel to the fibril axis. HADDOCK docking studies indicated that CR adopts a roughly planar conformation with the torsion angle Ï? characterizing the relative orientation of the two phenyl rings being a few degrees. In this study, we experimentally determine the torsion angle...
