Research Abstract

Protein misfolding occasionally leads to the formation of supramolecular assemblies known as amyloid fibrils, the deposition of which is associated with over 30 degenerative diseases. One of the most unique and essential properties of amyloid fibrils is their template-dependent growth, which underlies the propagation of pathology of amyloidoses. We have investigated a monomer-fibril complex of β_2-microglobulin formed transiently during the fibril growth by using Trp fluorescence and hydrogen/deuterium (H/D) exchange-NMR methods.
