The Oxidative Deamination of Sulfur Amino Acids by a Bacterial L-Amino Acid Oxidase
<p>The oxidative deamination of sulfur amino acids by a particulate L-amino acid oxidase obtained from an atypical Proteus rettgeri has been investigated. In addition to several sulfur amino acids tested here the enzyme catalyzes the oxidation of L-leucine, L-phenylalanine, L-tryptophan, …

Nutrient Utilization in Pigs and Chicks Treated With Lipopolysaccharide: Lysine, Threonine, Arginine, Sulfur Amino Acids and Vitamin E
… and decreases the absolute quantity of amino acids required for maximal protein accretion. The decreased need for amino acids is apparently due to a reduction in the chick's capacity to accrete protein, because LPS-injected chicks accreted less protein than saline-injected chicks. …

Interrelationships Among Sulfur Amino Acids, Choline and Betaine in the Chicken: Effects on Betaine-Homocysteine Methyltransferase Activity, Homocysteine Utilization and Choline Bioavailability
… basal diet containing soy protein isolate and 2-amino-2-methyl-1-propanol (an inhibitor of choline biosynthesis) was severely deficient in choline, and weight gain of chicks fed this diet responded to choline, but not methionine or betaine. In Assay 1, weight gain of chicks increased linearly …

Maintenance Requirements and Efficiency of Utilization of Protein, Threonine, Lysine and Sulfur Amino Acids in Chicks Fed Diets Based on Crystalline Amino Acids or Soybean Meal
… chicks were fed chemically defined crystalline amino acid diets containing graded levels of either L-threonine (Thr), L-lysine·HCl (Lys), DL-methionine (Met), or L-cystine (Cys) during the period 10 to 20-d posthatching. At least six doses of the limiting amino acid representing from 5 to …

Effects of Nutritional Manipulation on Poultry under Normal and Stressful Conditions
… has necessitated the frequent update of amino acid requirements to support this improvement. The first objective of this dissertation was to investigate the tryptophan requirement of laying hens in peak production and the lysine and sulfur amino acid requirements of broiler chicks under a …

Amino acid requirements and low crude protein, amino acid supplemented diets for swine and poultry
… this research was to determine requirements for amino acids that limit the use of crystalline amino acids, to determine the effects of reducing crude protein, and to evaluate the problems associated with low crude protein diets for swine and poultry. Four experiments were conducted to determine …

Enzymic extraction of protein from coconut flour (Cocos nucifera)
… degradation of structural polysaccharides. The amino acid composition or the control residue predicted ample room for possible improvement of the amino acid pattern in the enzyme-treated milk. The most limiting amino acids in the coconut milk preparation is lysine in confirmation of Butterworth …

The effect of nutrition and environment on broiler type chickens
Influence of light, dietary amino acid levels, feeding space, and ambient temperature on male broiler body weight, feed efficiency, percentage abdominal fat, and incidence and severity of leg abnormalities was studied in two experiments. Broilers subjected to intermittent light (1 hr on:2 hrs off) …

Chemical and molecular properties of processed soy proteins
… suggesting little destruction or oxidation of sulfur amino acids during hydrolysis. Time after extraction was found to affect the measured sulfhydryl and disulfide content. All processed soy products were found to contain cysteic acid. Soy isolates contained the highest amount of cysteic acid, …

Structural characterization of the Voltage-Dependent Selective Anion Channels (VDACs)
Cysteine and methionine residues are unique amino acids in proteins for their property to undergo several redox reactions as part of their normal function. Mitochondria are the cell source of most chemical energy obtained as the end-product of the aerobic oxidation of glucose. Mitochondria are also …

Dietary protein and bone health: Harmonizing conflicting theories
… the dietary acid load imposed by metabolism of sulfur containing amino acids into acid equivalents. Although alternate dietary sources of fixed acid cause demineralization of bone and apparent osteoporosis, this effect has not been consistently observed for protein, suggesting opposing, …

Determination of methionine and lysine requirements of growing broilers using the Ideal Protein Concept
… broiler chickens from 0 to 18 d of age. The mean amino acid ratios to Lys suggested by literature values were used in the formulation based on the Ideal Protein Concept. Six levels of Lys and eight levels of supplemental Met were used in the diets resulting in a total of 48 experimental …

Microbial pathways of sulfur metabolism and colorectal cancer risk
… bacteria metabolize organic and inorganic sulfur in order to produce H2S. We observed that microbes that metabolize organic sulfur distinguished AA CRC from NHW CRC subjects and AA controls. We hypothesize that SRB, (inorganic sulfur metabolizers), may impart beneficial functions, such as …
