TL;DR: The drastic change of the Cu(II) binding mode on going from neutral to weakly acidic conditions suggests that the micro-environmental pH in the brain cell regulates the Cu (II) affinity of the prion protein, which is supposed to undergo pH changes in the pathway from the cell surface to endosomes.
Abstract: The cellular form of prion protein is a precursor of the infectious isoform, which causes fatal neurodegenerative diseases through intermolecular association. One of the characteristics of the prio...

TL;DR: In this article, an analysis of visible spectrophotometric data was carried out using more than 100 copper(II) complexes formed by ligands with different coordination environments, and whose aim was the λmax value estimation for equatorially-coordinated copper-II complexes in solution.

TL;DR: The position of the absorption bands of the mixed species compared to those of the corresponding binary species was consistent with an increase of the ligand field due to an NH2 group entering into the coordination sphere of Cu(II).
