L-methioninase degrades methionine, which is essential in methionine-dependent cancer cells, resulting specific cell death. Normal cells can synthesize their own methionine amino acids even the absence of exogenous methionine. This selective targeting makes a promising therapeutic candidate for cancer. In this study, was partially purified from Brevibacterium linens BL2. The activity enzyme fou...

Methionine oxidation is used as a proxy to model the gamma radiation induced changes in single-use bags. These can be formation of acids, radicals and hydroperoxides due irradiation multilayer film single use bag made from. Biopharmaceutical polyethylene bags irradiated from 0 260 kGy aged 36 months were filled with methionine solution follow methionine. sulfoxide was measured using high perfor...

amino acid dehydrogenases (l-amino acid: oxidoreductase deaminating ec 1.4.1.x) are members of the wider superfamily of oxidoreductases that catalyze the reversible oxidative deamination of an amino acid to its keto acid and ammonia with the concomitant reduction of either nad+, nadp+ or fad. these enzymes have been received much attention as biocatalysts for use in biosensors or diagnostic kit...

Dietary methionine affects protein metabolism, lean gain and growth performance acts in the control of oxidative stress. When supplied large excess relative to requirements diets for pigs, positive effects on pork quality traits have been recently reported. This study aimed decipher molecular biochemical mechanisms affected by a dietary supply above loin muscle finishing pigs. During last 14 da...

This experiment was designed to investigate the effects of different levels copper–methionine chelates and alfalfa powder on egg yolk cholesterol content, quality, performance in laying hens. In this experiment, a total 100 hens (Nick Chick strain, from 109 117 weeks age) were arranged into five experimental treatments, consisting 2 dietary copper chelate (2x2) factorial completely randomized d...

the objective of this study was to evaluate the effects of supplementation of different level protein diets with rumen protected methionine and lysine on performance and ruminal parameters in holstein dairy cows when in their early lactation. twenty one dairy cows in their early lactations were assigned to three treatments in a randomized block design experiment of a 35-d duration period. diets...
