Abstract

Orientational inversion events of residues along the turn domains of amylin fibrils have been detected. This exceptional phenomenon has been observed in isolated amylin fibrils and in the cross-seeding amylin-Aβ and amylin-NAC fibrils. These new findings provide new avenues for detection of side chain flipping and side chain inversion events in turn domains and loops of various proteins.
