Alzheimer’s disease is a fatal neurodegenerative disorder involving the abnormal accumulation and deposition of peptides (amyloid-β, Aβ) derived from the amyloid precursor protein. Various factors that cause pathology data are revealed, but, at the moment, there is no clear understanding of the processes of plaque formation. This is interesting and actual problem because metals such as zinc, manganese,...
In this paper, binding of Mn2+ ions to the fragment of beta-amyloid peptide (Aβ13-23) was studied. Manganese complexation induces important structural changes within the C-terminal segment of the peptide. Investigation of peptide–metal ion binding was made by MnCl2 salt titration and recording 2D 1H–1H NMR TOCSY spectra (TOtal Correlation SpectroscopY). Multidimensional NMR techniques were performed...
