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.
谷氨酸和 EDTA 降低金属硫蛋白 3 的锌负荷均可加速 Cu(ii)淀粉样β4-16 向人 Zn7-金属硫蛋白 3 的铜转移。谷氨酸促进 Cu(ii)释放,Zn4-6-金属硫蛋白 3 反应更快。这些机制是累加的,证明了生物分子之间锌和铜转运的复杂相互关联网络。
