Abstract: The interaction between silver ion and apoCopC, CuN-CopC was investigated through different UV and fluorescence spectra in 10 mmol?L-1 Hepes, pH 7.4, at room temperature. Moreover, the supramolecular behavior between apoCopC, CuN-CopC, CopC-AgC , CuN-CopC-AgC and Vitamin B6 was further studied. The results suggested that the silver ion can occupied the Cu+ site in the 1:1 CopC-AgC complex and the binding constant is (1.68±0.33)×104mol?L-1. After binding of metal ions, the number of binding sites between different proteins and Vitamin B6 was reduced.
