Primary structure and spectroscopic studies of Neurospora copper metallothionein.
When Neurospora crassa is grown in the presence of Cu(II) ions, it accumulates the metal with the concomitant synthesis of a low molecular weight copper-binding protein. The molecule binds 6 g-atom of copper per mole protein (Mr = 2200) and shows a striking sequence homology to the zinc- and cadmium-binding vertebrate metallothioneins. Absorption, circular dichroism, and electron paramagnetic r...
متن کاملIdentification of metallothionein gene structure in sterlet (Acipenser ruthenus)
Aquatic organisms present, not only simple sources of accumulated metal, but can interact with metals, altering their toxicity. Due to exposition of biosphere with metals, organisms have developed various defense mechanisms to protect themselves against adverse effects of these ions and their compounds. Metallothionein (MT) is one of that which represents a critical mechanism for detoxification...

متن کاملStructure of mammalian metallothionein.
All mammalian metallothioneins characterized contain a single polypeptide chain of 61 amino acid residues, among them 20 cysteines providing the ligands for seven metal-binding sites. Native metallothioneins are usually heterogeneous in metal composition, with Zn, Cd, and Cu occurring in varying proportions. However, forms containing only a single metal species, i.e., Zn, Cd, Ni, Co, Hg, Pb, Bi...
متن کاملThe human metallothionein gene family: structure and expression.
Metallothioneins (MTs) are encoded by a multigene family in man. We have isolated those genes and analyzed the structure of some of them. The MT-II variant is encoded by a single functional gene: MT-IIA. The MT-IIB gene is a processed pseudogene derived from a reverse transcript of MT-II mRNA. On the other hand, the MT-I class of variants are encoded by a large number of genes, arranged in tand...
