Dossier Metallothioneins ■ Metallothioneins in the clam Ruditapes decussatus : an overview
The clam R. decussatus is a suspension-feeding bivalve mollusc widely distributed in European and Mediterranean coastal waters. Due to its economic importance it is extensively cultured in many countries, and particularly in Portugal where its production represents > 80 % of total shellfish production. The selection of the clam R. decussatus as a bioindicator was a consequence of its economic i...
متن کاملRole of metallothioneins in disease.
Metallothioneins are small proteins (6,000 to 10,000 mw) with similar amino acid compositions, high content of sulfhydryl amino acids and no aromatic amino acids. Emax at 250 nm is due to cadmium mercaptide bond. Synthesis is induced by a number of metals including zinc, cadmium, mercury, copper, bismuth, gold and silver. These proteins function as a mechanism of intracellular storage of some e...
متن کاملZeptomole Electrochemical Detection of Metallothioneins
BACKGROUND Thiol-rich peptides and proteins possess a large number of biological activities and may serve as markers for numerous health problems including cancer. Metallothionein (MT), a small molecular mass protein rich in cysteine, may be considered as one of the promising tumour markers. The aim of this paper was to employ chronopotentiometric stripping analysis (CPSA) for highly sensitive ...
متن کاملThe elusive function of metallothioneins.
Biochemistry and genetics are both required to elucidate the function of macromolecules. There is no question that metallothioneins (MTs) have unique biochemical properties, but genetic experiments have not substantiated the importance of MTs under physiological conditions. Even after thousands of studies describing the structure, biochemical characteristics, tissue distribution, induction, and...
