Journal ArticleDOI
Specific structure–stability relations in metallopeptides
TL;DR: In this article, the authors discuss the modes of coordination of oligopeptides by Cu(II) and Ni(II), and special attention is given to two general classes of peptides.
Journal ArticleDOI
Short peptides are not reliable models of thermodynamic and kinetic properties of the N‐terminal metal binding site in serum albumin
TL;DR: It was found that while qualitative aspects of interaction could be reproduced, the quantitative parameters could not, and a very strong influence of phosphate ions on the kinetics of Ni(II) interaction was found.
Journal ArticleDOI
Products of Cu(II)-catalyzed oxidation in the presence of hydrogen peroxide of the 1-10, 1-16 fragments of human and mouse β-amyloid peptide
TL;DR: The interactions of proteins with reactive oxygen species (ROS) may result in covalent modifications of amino acid residues in proteins, formation of protein-protein cross-linkages, and oxidation of the protein backbone resulting in protein fragmentation.
Journal ArticleDOI
The impact of the amino-acid sequence on the specificity of copper(II) interactions with peptides having nonco-ordinating side-chains.
TL;DR: Specific interactions that occur in complexes of Cu(II) ions with peptides composed only of amino acids with nonco-ordinating side chains are presented, with particular emphasis on stability constants of complexes, compared to oligoglycine or oligoalanine peptides.
Journal ArticleDOI
1-Hydroxyalkane-1,1-diyldiphosphonates as potent chelating agents for metal ions. Potentiometric and spectroscopic studies of copper(II) co-ordination

TL;DR: In this article, the steric effects as well as a high negative charge enforce unusual geometries around the metal ion and the formation of 1:2 complexes is less favourable.
