The influence of substrate benzhydroxamic acid (BHA) and iron ligand (cyanide) on the thermodynamics and dynamics of each of the two binding sites of horseradish peroxidase (HRP) isozyme C has been investigated by 1H NMR spectroscopy. A combination of line-width analysis and saturation transfer spectroscopy has allowed the direct determination of the(More)
The effect of low temperature on the protein metabolism of wheat primary leaves was examined. In seedlings transferred from 25 to 5 °C, total soluble protein accumulation, in vivo protein synthesis and breakdown, in vitro protein breakdown, and SDS-PAGE profiles of proteinases in gelatine-containing gels were analysed. Leaf protein content increased within(More)
We report on the galvanic deposition of Pt on Si from solutions containing PtCl(2) and different concentrations of HF. The results show that for low [HF]/[Pt] ratios (<or=26), only a thin layer of PtSi is formed. The deposition rate of Pt increases with [HF] in the plating solution, up to [HF]/[Pt] approximately 530; after this ratio, the morphology of the(More)
The substrate-bound form of the enzyme heme oxygenase (HO), which catalyzed the stereospecific alpha-meso bridge cleavage of hemin to yield biliverdin IX alpha, has been investigated by 1H NMR in both its primarily high-spin and its cyanide-inhibited low-spin forms. Both derivatives yield 1H NMR spectra indicative of extensive heterogeneity that is largely(More)
1. A procedure for the purification of factor V from bovine plasma with a good yield and in a high state of purity is described. The isolation procedure involves BaSO4, adsorption, chromatography of the absorbed plasma on DEAE-Sephadex A-50, activation with thrombin of the A-50 eluate, chromatography on Amberlite CG-50 and precipitation with (NH4)2SO4.(More)
