Selective selC-independent selenocysteine incorporation into formate dehydrogenases. [PDF]
PLoS ONE, 2013 The formate dehydrogenases (Fdh) Fdh-O, Fdh-N, and Fdh-H, are the only proteins in Escherichia coli that incorporate selenocysteine at a specific position by decoding a UGA codon.

Deciphering the Role of Selenoprotein M
Antioxidants, 2023 Selenocysteine (Sec), the 21st amino acid, is structurally similar to cysteine but with a sulfur to selenium replacement. This single change retains many of the chemical properties of cysteine but often with enhanced catalytic and redox activity ...

Selenoprotein: Potential Player in Redox Regulation in Chlamydomonas reinhardtii
Antioxidants, 2022 Selenium (Se) is an essential micro-element for many organisms, including Chlamydomonas reinhardtii, and is required in trace amounts. It is obtained from the 21st amino acid selenocysteine (Sec, U), genetically encoded by the UGA codon.

Environmental and Circadian Regulation Combine to Shape the Rhythmic Selenoproteome
Cells, 2022 The circadian clock orchestrates an organism’s endogenous processes with environmental 24 h cycles. Redox homeostasis and the circadian clock regulate one another to negate the potential effects of our planet’s light/dark cycle on the generation of ...

Chlorophyllin Inhibits Mammalian Thioredoxin Reductase 1 and Triggers Cancer Cell Death
Antioxidants, 2021 Food colorants are widely used by humans in food production and preparation; however, their potential toxicity requires an in-depth analysis. In this study, five out of 15 commercial food colorants, namely, lutein, betanin, caramel, crocin and ...

Indirect Routes to Aminoacyl-tRNA: The Diversity of Prokaryotic Cysteine Encoding Systems
Frontiers in Genetics, 2022 Universally present aminoacyl-tRNA synthetases (aaRSs) stringently recognize their cognate tRNAs and acylate them with one of the proteinogenic amino acids.
