Inhibition of amyloid fibril formation in the variable domain of λ6 light chain mutant Wil caused by the interaction between its unfolded state and epigallocatechin-3-O-gallate

ConclusionsInhibition of amyloid fibril formation of Wil was caused by 1) EGCG binding to unfolded state rather than folded state and 2) chemical modifications of Wil by auto oxidation of EGCG.General significanceIn the competitive formation of amyloid fibrils and off-pathway oligomers, EGCG produces the latter immediately after it preferentially binds to the unfolded state. It may be general mechanism of EGCG inhibition for amyloidosis.Graphical abstract
