Metallothionein and Metallothionein-Like Proteins: Physiological Importance
1989Since the initial demonstration of a low-molecular weight cadmium-binding protein in mammals, the research on the function of these proteins, which also can bind Cu, Zn, and Hg, has been focused primarily on their detoxifying properties. Such a direction is understandable, since the synthesis of the proteins can be induced by these potentially toxic ...

The bacterial metallothioneins (MT), BmtAs, constitute a well defined sub-family, sharing a number of characteristics with eukaryotic metallothioneins. They are small, cysteine-rich proteins, are inducible by metal ion stress, and contain metal-thiolate clusters with topologies similar to those of mammalian MTs. They also have a number of features that

Metallothioneins (MTs) are small cysteine-rich proteins that bind multiple metal ions in characteristic metal-thiolate clusters. They have been identified and studied in both prokaryotes, where they seem to be limited to a relatively small number of genera, and eukaryotes, where they are nearly ubiquitous. These are the archetypal cytosolic binders and

Copper Coordination in Metallothionein
1987Metal ions in Cd,Zn-metallothionein (MT) are ligated in 2 polynuclear clusters enfolded by separate domains (1–3). The 7 metal ions are tetrahedrally coordinated to 4 cysteine thiolates (4,5). Eight of the 20 ligating cysteines exist as bridging sulfurs in the clusters (5).

Dipterean insecta owe their relevance to the well-known model organism D. melanogaster, and extensively to the Drosophila genus. In the frame of the study of metallothioneins (MTs), they constitute a bizarre exception, since Drosophila is the only metazoan organism synthesizing only MTs similar to the yeast (S.
