Cu transfer from amyloid-β4–16 to metallothionein-3: the role of the neurotransmitter glutamate and metallothionein-3 Zn(ii)-load states

Abstract

Copper transfer from Cu(II)amyloid-β4–16 to human Zn7-metallothionein-3 can be accelerated by glutamate and by lowering the Zn-load of metallothionein-3 with EDTA. Glutamate facilitates the Cu(II) release, and Zn4–6-metallothionein-3 react more rapidly. These mechanisms are additive, proving the intricate and interconnected network of zinc and copper trafficking between biomolecules.
