Abstract

Ligand competition with a number of chromophoric probes were used to determine the binding affinities for [Zn.sup.II] and [Cu.sup.I] of each metal-binding domain (MBD). The obtained information highlighted the potential toxicity of [Cu.sup.+] in vivo and more sensitive magnitude of copper sensor proteins compared to zinc sensor proteins.
