Arabidopsis gene and cDNA encoding cell-wall invertase.
Suc is the final product of photosynthesis, but before it can be utilized it must be cleaved into hexoses either by invertase (0-fructofuranosidase, EC 3.2.1.26) or by SUC synthase (EC 2.4.1.13). There are three recognized types of invertase present in plant cells: soluble neutra1 invertase, soluble acid invertase, and insoluble cell-wall acid invertase. Invertase genes encoding cell-wall and v...
متن کاملPreconcentration of lead with Amberlite XAD-2 and Amberlite XAD-7 based chelating resins for its determination by flame atomic absorption spectrometry.
Four chelating matrices prepared by coupling Amberlite XAD-2 with chromotropic acid (AXAD-2-CA or 1), pyrocatechol (AXAD-2-PC or 2) and thiosalicylic acid (AXAD-2-TSA or 3) through azo spacer and impregnation of Amberlite XAD-7 with xylenol orange (AXAD-7-XO or 4) have been studied for enrichment of lead(II). All the four resins quantitatively sorb Pb(II) at pH 3.0-8.0 when the flow rate is mai...
متن کاملA second cell wall acid invertase gene in Arabidopsis thaliana.
Invertases, or P-fructofuranosidases, hydrolyze SUC into Fru and Glc. Immobilized acid invertases in plants have been described as localized in the cell wall (Eschrich, 1980; Gogarten, 1986; Sturm and Chrispeels, 1990). Soluble acid invertases were ascribed to the vacuole (Leigh et al., 1979). At least in dicotyledonous plants these organelle-specific isoforms are encoded by separate genes (Stu...
متن کاملRemoval of Acid-soluble Lignin from Biomass Extracts Using Amberlite Xad-4 Resin
This paper describes a method for the removal of acid-soluble lignin from acid-hydrolyzed hemicelluloses extracted from a mixture of northern US hardwood chips, by using Amberlite XAD-4 resin, which was shown to remove 100% of furan derivatives and 90% of acid-soluble lignin. Subsequent fermentation of the resin-treated hydrolyzates gave ethanol yields as high as 97% of theoretical and showed a...
متن کاملSynthesis and application of Amberlite xad-4 functionalized with alizarin red-s for preconcentration and adsorption of rhodium (III)
A new chelating resin was prepared by coupling Amberlite XAD-4 with alizarin red-s through an azo spacer, characterized by infra-red spectroscopy and thermal analysis and studied for Rh(III) preconcentration using inductively coupled plasma atomic emission spectroscopy (ICP-AES) for rhodium monitoring in the environment. The optimum pH for sorption of the metal ion was 6.5. The sorption capacit...
