Selenomethionine as an Antioxidant

Nature, 1961
EVIDENCE has accumulated indicating that: (1) vitamin E functions, at least in part, as a lipid antioxidant; (2) unrelated substances having antioxidant activity can alleviate or prevent some of the symptoms of vitamin E deficiency1; (3) selenium compounds also can alleviate or prevent some of the symptoms of vitamin E deficiency2; (4) the ingestion of

Selenomethionine in Enzymatic Transmethylations

Nature, 1957
IN the past, biological interest in selenium has been centred around its toxic role as the cause of ‘alkali disease’ and ‘blind staggers’1 and as a source of industrial poisoning2. However, recent developments suggest a more important role for this element.

One-electron reduction of selenomethionine oxide

Free Radical Research, 2000
Experimental evidence is provided that selenomethionine oxide (MetSeO) is more readily reducible than its sulfur analogue, methionine sulfoxide (MetSO). Pulse radiolysis experiments reveal an efficient reaction of MetSeO with one-electron reductants, such as e(aq)-, (k = 1.2x10(10) M(-1) s(-1)), CO2*- (k = 5.9x10(8) M(-1) s(-1)) and (CH3)2 C*OH (k = 3 ...

Synthesis and analysis of selenomethionine metabolites

Analytical Biochemistry, 1989
This paper describes the enzymatic synthesis of selenomethionine metabolites of the transmethylation and polyamine synthesis pathways: adenosylselenomethionine, adenosylselenohomocysteine, decarboxylated adenosylselenomethionine, and methylselenoadenosine.

Selenomethionine Labeling of Recombinant Proteins

2007
Selenomethionine incorporation is a standard method for determining the phases in protein crystallography by single- or multiwavelength anomalous dispersion. Recombinant expression of selenomethionine-containing protein in non-auxotrophic Pichia pastoris strains yield an incorporation of about 50%.
