Isolation and characterization of valine dehydrogenase from Streptomyces aureofaciens.
Valine dehydrogenase was purified to homogeneity from the crude extracts of Streptomyces aureofaciens. The molecular weight of the native enzyme was 116,000 by equilibrium ultracentrifugation and 118,000 by size exclusion high-performance liquid chromatography. The enzyme was composed of four subunits with molecular weights of 29,000. The isoelectric point was 5.1. The enzyme required NAD+ as a...
متن کاملVibrational spectroscopic studies of L,D-alternating valine peptides
Raman and infrared spectra of Boc-(L-Val-D-Val),-OMe [(LD-Val),], with n = 4, 6 and 8, were obtained in crystalline and solution states. Based on predictions from normal-mode calculations of a number of relevant singleand double-stranded p-helix conformations, structures were assigned for the three oligopeptides under the abovementioned conditions. In the crystalline state, all three oligopepti...
متن کاملTHE SOLUBILITY OF d-VALINE IN WATER
1. The solubility of d-valine in water has been determined over a range of 0-60 degrees . 2. The solubility of this amino acid varies with the mode of crystallization, indicating a dependence of solubility on the crystal form.
متن کاملValine for Lactation
An experiment was conducted using production and metabolic criteria to estimate the valine requirement of the lactating sow. Ground corn, gelatin, corn sugar, vitamins, minerals and indispensable amino acids were used to formulate a diet containing all the essential nutrients except valine. L-valine was added to provide .23 (basal), .38, .53, .68 and .83% valine. Twenty-five mature Landrace • Y...
متن کاملValine Ameliorates Liver Fibrosis
It has been reported that treatment with branched chain amino acids (BCAAs) increases the survival rates in cirrhotic patients. In this study, we investigated the effect of L-valine, one of BCAAs, on liver fibrosis in rat. To induce liver fibrosis, male Wistar rats were injected carbon tetrachloride (CCl4) intraperitoneally (2.0 mL/kg) twice a week for 12 weeks. The rats (seven to fifteen rats ...
