Basicity of N-Terminal Amine in ATCUN Peptide Regulates Stability Constant of Albumin-like Cu~(2+) Complex

摘要

We quantitatively investigated the coordination ability of ATCUN peptides possessing various amino acid residues on the N-terminal side of the third histidine, toward Cu~(2+). We discovered that the stability of the Cu~(2+)-ATCUN complex was governed by the acidity of the N-terminal amino nitrogen in the peptides.
