In an attempt to reveal the mechanism of rats' resistance to Alzheimer's disease, we determined the structure of the metal-binding domain 1–16 of rat β-amyloid (rat Aβ(1–16)) in solution in the absence and presence of zinc ions. A zinc-induced dimerization of the domain was detected. The zinc coordination site was found to involve residues His-6 and His-14 of both peptide chains. We used experimental...
Zinc-induced aggregation of amyloid-β peptide (Aβ) is a hallmark molecular feature of Alzheimer's disease. Here we provide direct thermodynamic evidence that elucidates the role of the Aβ region 6–14 as the minimal Zn2+ binding site wherein the ion is coordinated by His6, Glu11, His13, and His14. With the help of isothermal titration calorimetry and quantum mechanics/molecular mechanics simulations,...
