2761“…Chemical shift data have shown that all Cd ions are tetrahedrally coordinated to four cysteine thiolate ligands with single cysteinyl sulfurs bridging adjacent metals. Homonuclear decoupling experiments have shown that the 7 g-atoms of metal bound per mole of mammalian protein are located in a three- and a four-metal cluster while the 6 g-atoms of metal in the invertebrate MT are located in two three-metal clusters. …”
