Selenoprotein synthesis in archaea
BioFactors, 2001AbstractThe availability of the genome sequences from several archaea has facilitated the identification of the encoded selenoproteins and also of most of the components of the machinery for selenocysteine biosynthesis and insertion. Until now, selenoproteins have been identified solely in species of the genera Methanococcus (M.) and Methanopyrus ...

Selenoproteins and maternal nutrition
Comparative Biochemistry and Physiology Part B: Biochemistry and Molecular Biology, 2008Selenium (Se) is an essential trace element of fundamental importance to health due to its antioxidant, anti-inflammatory and chemopreventive properties attributed to its presence within at least 25 selenoproteins (Sel). Sel include but not limited to glutathione peroxidases (GPx1-GPx6), thioredoxin reductases (TrxR1-TrxR3), iodothyronine deiodinases ...

Update on Selenoprotein Biosynthesis
Antioxidants & Redox Signaling, 2015Significance: Selenium is an essential trace element that is incorporated in the small but vital family of proteins, namely the selenoproteins, as the selenocysteine amino acid residue. In humans, 25 selenoprotein genes have been characterized.

Selenoproteins in bladder cancer
Clinica Chimica Acta, 2012Selenoproteins with genetically encoded selenium (Se) are very important in response to oxidative stress, redox balance and regulation of various metabolic and developmental processes. Although increased circulating Se has been associated with 33% risk reduction of bladder cancer, there are little data on selenoprotein expression at the protein and ...

Purification of selenoprotein W (Se-W) from rat and monkey muscles was shown to exist in multiple forms: with or without reduced glutathione and/or a 41-Da moiety (identity still unknown). TGA is located at coding position 13 in Se-W complementary DNA (cDNA) from all five species studied (rats, mice, sheep, human and monkey). TGA is also the stop codon

Identity, evolution and function of selenoproteins and selenoprotein genes
2001UGA has a dual role in the genetic code serving as a signal for termination and a codon for selenocysteine (Sec). Sec appears to have been added to the already existing genetic code and its use has accumulated during evolution of eukaryotes culminating in vertebrates.

Selenium, Selenoproteins and Vision
2005Selenium biochemistry is reviewed in respect to its presumed relevance to age-related ocular diseases. Selenium is an essential trace element that exerts its physiological role as selenocysteine residue in at least 25 distinct selenoenzymes in mammals. Lack of GPx-1 due to alimentary selenium deprivation has been inferred to induce cataract in rats and
