Living organisms use selenium mainly in the form of selenocysteine in the active site of oxidoreductases. Here, selenium’s unique chemistry is believed to modulate the reaction mechanism and enhance the catalytic efficiency of specific enzymes in w

Selenoprotein P (SELENOP) is a serum glycoprotein that is required for proper selenium distribution in mammals, particularly in supplying selenium to the brain and testes. As the sole mechanism for providing essential selenium to developing spermatoz

Although several experimental studies showed cancer-preventive efficacy of supplemental dietary selenium, human clinical trials questioned this efficacy. Identifying its molecular targets and mechanism is important in understanding this discrepancy.

This editorial shortly summarizes the highlights described in the Forum, novelties about selenoproteins. Two articles describe the selenoprotein biosynthesis and the role of so far identified proteins involved, including that of selenocysteine-β-lya

Selenium is present in proteins in the form of selenocysteine, where this amino acid serves catalytic oxidoreductase functions. The use of selenocysteine in nature is strongly associated with redox catalysis. However, selenium is also found in a 2-se

Selenium is a metalloid and exerts its biological functions mainly through selenoproteins. The incorporation of selenium into the selenoproteins is in the form of selenocysteine and mediated cotranslationally. Selenoproteins include three enzyme fami
