Models of copper–protein interaction: copper(II) complexes of glycyl-L-histidylglycine in solution and in the crystalline state
Abstract
X-Ray structure analysis shows that crystals of copper(II) and glycylhistidylglycine (HA) consist of a three-dimensional network which contains 40% disordered water located in channels limited by rings of six dimers, (Cu2H-2A2)6; and, as shown by e.m.f. data and small angle X-ray scattering, a very similar species exists in solution.
