Cysteine and glutathione trigger the Cu-Zn swap between Cu(ii)-amyloid-β4-16 peptide and Zn7-metallothionein-3


Santoro, Alice; Ewa Wezynfeld, Nina; Vašák, Milan; Bal, Wojciech; Faller, Peter (2017). Cysteine and glutathione trigger the Cu-Zn swap between Cu(ii)-amyloid-β4-16 peptide and Zn7-metallothionein-3. Chemical Communications, 53(85):11634-11637.

Abstract

Cysteine and glutathione are able to reduce Cu(ii) coordinated to the peptide amyloidβ4-16, and shuttle the resulting Cu(i) to partially replace Zn(ii) in the protein Zn7-metallothionein-3. The released Zn(ii) in turn binds to amyloid-β4-16. Thus cysteine and glutathione are modulators of Cu/Zn-distribution between metallothionein-3 and amyloid-β4-16.
