Tuning the Redox Properties of Copper(II) Complexes with Amyloid-β Peptides
Source abstract
Abstract
Copper complexes of metal binding domains of synthesized amyloid-β peptides – Aβ(1-16) and N-truncated Aβ(4-16) containing a novel N-terminal FRH sequence, as well as its shorter mutants were characterized by cyclic voltammetry. The influence of the peptide sequence and peptide to copper molar ratio on the electrochemical properties of the obtained structures were studied and discussed. The reversibility of the studied redox processes in copper complexes with Aβ(4-x) derivatives was also investigated. The results indicate the crucial role of Tyr10 in the redox process of the Aβ(4-x) complex, including the removal of reversibility of the Cu(II)/Cu(III) redox couple.
