Plant Metallothioneins: Putative Functions Identified by Promoter Analysis in Silico
Metallothioneins are low-molecular-weight proteins capable of covalently binding heavy metal ions due to the presence of many cysteine residues in their sequences. We analyzed the predicted amino acid sequences of 19 metallothionein (7 from Arabidopsis thaliana and 12 from Oryza sativa) and their promoter sequences in silico in order to determine the potential regulatory cis-elements present in...
متن کاملDossier 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 کاملEquine Hepatic and Renal Metallothioneins
An improved, simplified, and greatly shortened isolation procedure for metallothionein from tissue extracts using gel filtration (Sephadex G-SO) and DEAE-cellulose chromatography is presented. When isolated by this procedure, the molecular weight of both the liver and kidney metalloproteins is found to be about 6600, as determined by equilibrium centrifugation and gel filtration. The amino acid...
متن کاملDiversity and distribution of plant metallothioneins: a review of structure, properties and functions.
More than 30 years have passed since the discovery of the first plant metallothionein in wheat embryos, from which the emergence of a uniquely diverse metallothionein family with a fascinating array of structural nuances and molecular properties has been witnessed. Metallothioneins are not only constitutively expressed, but the production of different types of plant metallothionein is also stim...
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...
