Mutations and post-translational modifications of amyloid-β (Aβ) peptide in its N terminus have been shown to increase fibril formation, yet the molecular mechanism is not clear. Here we investigated the kinetics of the interactions of copper with two Aβ peptides containing Familial Alzheimer's disease (FAD) mutations (English (H6R) and Tottori (D7N)), as(More)
The kinetics of the interactions between amyloid-β (Aβ) and metal ions are crucial to understanding the physiological and pathological roles of Aβ in the normal brain and in Alzheimer's disease. Using the quenching of a fluorescent probe by Cu(2+), the mechanism of Aβ/Cu(2+) interactions in physiologically relevant conditions has been elucidated. Cu(2+)(More)
