Recombinant Protein Production in Bacillus Species, Isolation and Methionine Production in Methionine-producing Microorganisms
… m></em></em></em></em></em></em></em></em></p> <p>Methionine is the first limiting amino acid in poultry feed and must be supplemented to the poultry feed mixture. Many studies attempted to isolate methionine producing microoragnisms from environments and genetically modified by using chemical …

Methionine bioassays and methionine-choline-sulfate relationships in practical-type diets for young turkeys
… to determine the relative potencies of four methionine compounds on an equimolar basis. A 28% protein basal diet composed primarily of ground yellow corn, dehulled soybean meal, and meat and bone meal was supplemented with DL-methionine (DL), sodium salt of DL-methionine (MENA), methionine …

Selective Protein Functionalisation at Methionine
… abundance and ancillary protein function of methionine, selective functionalisation of this amino acid presents an opportunity to develop a strategy complementary to current technologies. Strategies targeting methionine remain under-explored, with few truly biocompatible methods reported to …

Effects of ingestion of milk and methionine on blood levels of tryptophane and methionine in dairy calves
… The blood plasma levels of tryptophane and methionine were determined by microbiological assay. It was found that the blood plasma levels of tryptophane and methionine varied considerably at different time intervals after feeding milk. One calf was fed 50 grams dl-methionine with its regular …

Oxidation of methionine residues in protein pharmaceuticals
(cont.) of free methionine. Therefore, the environments surrounding different methionine sites in G-CSF mainly provide spatial restriction to the access to the solvent but do not affect oxidation in a specific manner, consistent with the good correlation between 2SWCN's and the rates of oxidation. …

An evaluation of supplemental methionine sources for lactating dairy cows
<p>The most effective method for increasing supplies of MP-Met to dairy cows to increase milk protein production is to feed rumen-protected Met ( RP-Met) products; however, not all RP-Met products are absorbed by the dairy cow in the same manner. Universally acceptable methods must be developed to …

Methionine Sulfoxide Reductase and Ubiquitin-dependent Degradation of Alpha-synuclein
… on elevated dopamine and 14-3-3 levels in the methionine sulfoxide reductase A (MsrA) knockout mouse brain, as well as decreased αSyn degradation in MsrA KO yeast cells. Hence, this study will focus on the interactions among MsrA, αSyn degradation, 14-3-3 proteins, and Ub. Here we show that …

Methanocaldococcus jannaschii and the Recycling of S-adenosyl-L-methionine
S-Adenosyl-L-methionine (SAM) is an essential metabolite for all domains of life. SAM- dependent reactions result in three major metabolites: S-adenosyl-L-homocysteine (SAH), methylthioadenosine (MTA), and 5'-deoxyadenosine (5'-dA). Each of these has been demonstrated to be feedback inhibitors of …

Design and synthesis studies of new s-adenosyl-l-methionine analogues
S-Adenosyl-L-Methionine (SAM), which is involved in methyl group transfers, is the second most abundant coenzyme in the human body. It is made from adenosinetriphosphate (ATP) and methionine catalyzed by adenosyltransferase. Methyltransferases (MTs) transfer the activated methyl group from the …

Effect of Soy Protein, Isoflavones and Methionine Supplementation on Lipid Metabolism
… of soy protein, dietary isoflavones and methionine supplementation as possible hypocholesterolemic agents. Results from our time course experiment indicated that gerbils fed casein had higher serum total cholesterol concentrations compared to gerbils fed alcohol-washed, essentially …

Characterization of methionine transport in bovine intestinal brush border membrane vesicles
Characteristics of methionine uptake by brush border membrane vesicles of bovine small intestine were investigated. Alkaline phosphatase marked the brush border membrane fraction obtained through differential centrifugation followed by a sucrose gradient. This preparation yielded a 10-fold …

Physiological and Biochemical Aspects of Methionine Isomers and Precursors in Broilers
Methionine (Met) is an essential amino acid for animals and also the first limiting amino acid in a broiler diet. The dietary supplemental Met sources include the natural isoform L-methionine (L-Met), the synthetic form DL-methionine (DL-Met) and the synthetic Met precursor DL-2-hydroxy-4 …

The Reaction of a Water Soluble Platinum Compound with Methionine and Derivatives
… oxalate. This complex has been reacted with methionine and N-acetylmethionine at different molar ratios. At high Pt: methionine ratios, chelates with the sulfur and nitrogen atoms of the methionine are dominant; at lower Pt: methionine ratios, a bis-methionine product is formed. The en ligand …

Protected Methionine and Heat-Treated Soybean Meal for High-Producing Dairy Cows
<p>The effectiveness of a rumen-protected methionine preparation was studied as an amino acid source for high-producing dairy cows during wk 4 through 16 postpartum. Twenty-four Holstein cows (14 primiparous and 10 multiparous) were fed concentrate containing heat-treated· soybean meal without or …

Prediction of Methionine Retention During the Extrusion Processing of Fortified Soybean Systems
Successful methionine fortification of soy can enhance the nutritional quality of soy proteins. Methionine, however, is highly sensitive to processing conditions, hence the need for kinetic studies to optimize its retention. To establish general kinetic models, it is critical to determine the …
