Biological analogs. Nature of the binding sites of copper-containing proteins
摘要：
An extended series of ligands and their copper(II) complexes have been prepared as spectroscopic models for determining the geometries and ligand coordinations of copper proteins. The electronic properties of thioether, imidazole, amide anion, amine, phenolate anion, and thiolate anion coordination to copper(II) have been determined. In addition, the electronic spectra of some of these ligands in square-planar, square-pyramidal, and tetrahedral geometries about copper(II) have been obtained by appropriate ligand design. On the basis of these results and an analysis of the protein spectra, structures for the copper coordination and geometry in (blue) type I copper, copper in galactose oxidase, type III copper, and copper in oxyhemocyanin are proposed.
