Selenium metabolism and renal disease

Journal of Renal Nutrition, 1997
Abstract Selenium's most well-established role is as a component within the active site of the antioxidant enzyme, glutathione peroxidase. Glutathione peroxidase helps prevent the generation of free radicals and decreases the risk of oxidative damage to tissues, including the kidney and its vascular components.

Selenium metabolism in bacteria

2001
The biosynthesis and specific incorporation of selenocysteine into protein in bacteria requires the function of two cis and four trans elements. The cis elements are a UGA codon determining the position of selenocysteine insertion into the nascent polypeptide and a secondary/tertiary structure within the mRNA, designated the SECIS element, following ...

Metabolism of Selenium

1983
Selenium is absorbed from the gastrointestinal tract to various extents, and the distribution within the body varies with the species and with the chemical form and the amount of the element ingested.

Selenium: metabolism and endocrines (Minireview).

Endocrine regulations
Selenium occurs both in prokaryocytes and eukaryocytes as a component of selenoenzymes or selenoproteins. Approximately 80 % of selenium in animal or human body occurs in the form of seleno-L-cysteine, an amino acid encoded by one of standard termination codons. Selenium is an integral component of the active site of glutathione peroxidases which plays

Metabolic and functional defects in selenium deficiency

Philosophical Transactions of the Royal Society of London. B, Biological Sciences, 1981
This paper is concerned with present-day knowledge of the biological role of selenium, of its interaction with other nutrients including trace elements, and with the importance of selenium in human nutrition and health. Selenium has been shown to be an integral part of glutathione peroxidase, which catalyses the reduction of a large range of lipid ...

[Selenium in peroxide metabolism].

Medizinische Klinik (Munich, Germany : 1983), 1997
Out of the growing number of so far known mammalian selenoproteins four are peroxidases. Their common catalytic mechanism involves redox shuttling of a selenocysteine residue in the active site, where it forms a characteristic catalytic triad with hydrogen-bonded tryptophan and glutamine residues.
