Influence of valine flooding on channeling of valine into tissue pools and on protein synthesis

American Journal of Physiology-Endocrinology and Metabolism, 1995
Rates of valine incorporation into protein were measured under control and valine-"flooding" conditions and included correction for the degree of recycling of unlabeled valine derived from the steady-state breakdown of tissue protein into the precursor pool (tRNA bound).

Study of the Coordinated System Cd(II)-Valine-Valinate Ion

Collection of Czechoslovak Chemical Communications, 1992
The polarographic method has been applied to the study of the coordinated systems Cd(II)-neutral valine and Cd(II)-valinate ion in aqueous medium and I = 1.0 mol l-1 (NaClO4). The stability constants of the complexes were determined as: [Cd(HV)]2+ (β10 = 7 ± 0.5), [Cd(HV)2]2+ (β20 = 24 ± 4), [Cd(HV)3]2+ [β30 = (1.5 ± 0.32) . 102], [Cd(V-)]+ [β01 = (4.1

Regulation of Isoleucine and Valine Biosynthesis

1978
Publisher Summary This chapter discusses the regulation of isoleucine and valine biosynthesis. Isoleucine and valine biosynthesis is a model system for the study of mechanisms by which the cell coordinates different parts of its total metabolism. Threonine deaminase is the first enzyme in isoleucine biosynthesis.

Production of valine by aBacillus sp.

Zeitschrift für allgemeine Mikrobiologie, 1978
AbstractA bacterium isolated from Burdwan (India) soil was found to accumulate l‐valine in the growth medium and identified to be a strain of Bacillus subtilis. The strain is able to grow and accumulate valine in a purely synthetic medium, but supplementation of the synthetic medium with either Casamino acids or yeast extract or with both ...

Valine Requirement of the Growing Kitten

The Journal of Nutrition, 1977
The valine requirement of the kitten was studied using a crossover design with two groups of three weanling kittens. The kittens were fed a semipurified diet containing only free amino acids as a source of nitrogen containing 0.0%, 0.6%, or 1.8% valine.

The Neurotoxicity of Valine Deficiency in Rats

The Journal of Nutrition, 1978
When valine, an essential amino acid, was withdrawn from the diet of weanling rats, the animals rapidly developed a unique pattern of neurological symptoms characterized by head retraction, staggering and aimless circling. At necropsy degenerative changes were most prominent in the neurons of the red nuclei, brain stem structures which modulate motor ...

Inhibition of valine utilization by cyclobutaneglycine

Archives of Biochemistry and Biophysics, 1977
Abstract dl -Cyclobutaneglycine formed by basic hydrolysis of 5-cyclobutylhydantoin prevents the growth of Escherichia coil W in an inorganic salts-glucose medium. This inhibitory effect of the amino acid analog is reversed in a competitive manner over a wide range of concentrations specifically by l -valine.

Valine requirement of the finishing pig2

Journal of Animal Science, 1995
Pigs weighing approximately 70 kg were used in two experiments to determine the valine requirement during the finishing period. In the first experiment, 10 gilts were allotted in two 5 x 5 Latin square designs to five semipurified diets that ranged in valine concentration from .35 to .55%.

Valine is a precursor of propionyl-CoA

Trends in Biochemical Sciences, 1992
For some time the metabolism of valine has been misrepresented by several biochemistry textbooks. This article demonstrates that propionyl-CoA occurs as an intermediate in the valine metabolic pathway before the formation of methylmalonyl CoA.

Possible Transition in D-Valine and L-Valine Single Crystal Samples

Chinese Physics Letters, 1995
The specific heats and temperature dependence of the x-ray powder diffractions for the D-valine and the L-valine single crystal samples have been studied. It is found that there is a specific heat jump at 272.0 K for the D-valine samples but no jump at the same temperature for the L-valine sample.
