Methionine Dependence of Cancer
Biomolecules, 2020 Tumorigenesis is accompanied by the reprogramming of cellular metabolism. The shift from oxidative phosphorylation to predominantly glycolytic pathways to support rapid growth is well known and is often referred to as the Warburg effect.

Characterization of methionine oxidation and methionine sulfoxide reduction using methionine-rich cysteine-free proteins [PDF]
BMC Biochemistry, 2012 Abstract Background Methionine (Met) residues in proteins can be readily oxidized by reactive oxygen species to Met sulfoxide (MetO). MetO is a promising physiological marker of oxidative stress and its inefficient repair by MetO reductases (Msrs) has been linked to neurodegeneration and aging. Conventional methods of

Methionine metabolism, functions, and application in swine
Animal NutritionMethionine (Met) is the only sulfur-containing essential amino acid for animals and is the second or third limiting amino acid in swine diets. It plays a role not only in protein synthesis, but also as an important methyl donor to participate in various ...

Kinetics and mechanism of the oxidation of methionine by quinolinium chlorochromate [PDF]
Journal of the Serbian Chemical Society, 2005 The oxidation of methionine by quinolinium chlorochromate (QCC) has been studied, in the presence of chloroacetic acid, and in water-acetic acid mixtures of varying mole fractions. The reaction is first order with respect to methionine, QCC and acid. The

Methionine sulfoxide reductase contributes to meeting dietary methionine requirements [PDF]
Archives of Biochemistry and Biophysics, 2012 Methionine sulfoxide reductases are present in all aerobic organisms. They contribute to antioxidant defenses by reducing methionine sulfoxide in proteins back to methionine. However, the actual in vivo roles of these reductases are not well defined.

Developments in plant breeding for improved nutritional quality of soya beans I. Protein and amino acid content [PDF]
, 2000 Soya beans, like other legumes, contain low concentrations of the nutritionally essential sulphur amino acid, methionine. Cysteine, although not an essential amino acid because it can be synthesized from methionine, also influences the nutritional ...

Reduction of methionine sulfoxide to methionine by Escherichia coli [PDF]
Journal of Bacteriology, 1979 L-Methionine-dl-sulfoxide can support the growth of an Escherichia coli methionine auxotroph, suggesting the presence of an enzyme(s) capable of reducing the sulfoxide to methionine. This was verified by showing that a cell-free extract of E. coli catalyzes the conversion of methionine sulfoxide to methionine.
