Regulation of taproot development and sucrose stabilization in sugar beet: Influence of invertase inhibitors and occurrence of mitochondrial energy-dissipating proteins
… Enzyme bestimmt. Die Aktivität von Invertasen zeigt eine negative Korrelation zur Saccharoseanreicherung und während des Großteils der Speicherwurzelentwicklung werden lediglich Isoformen der Saccharose-Synthase und keine Invertasen exprimiert. Nach Verwundung werden eine …

Sucrose breakdown in the potato tuber
… zytosolischen Expression einer Hefe-Invertase auf den Metabolismus der Kartoffelknolle zu untersuchen. Die beobachteten Unterschiede zwischen induzierter und konstitutiver Expression der Invertase führten zu der Feststellung, dass die Glycolyse erst induziert wird nachdem ein …

Functional genomics of plant compensatory responses
… potential candidate genes viz., G6PDH1 and invertase. These genes were then characterized using recombinant DNA techniques. A set of recombinant inbred lines developed from a cross between Columbia X Landsberg erecta, of the annual plant Arabidopsis thaliana were screened initially to …

An investigation of the physiological roles and enzymatic properties of invertases in tobacco and hybrid poplar
Plant invertases (EC 3.2.1.26) represent a multi-gene family of β-fructofuranosidases that perform integral roles in several biochemical processes. The central importance of this family of enzymes to plant growth and development has made them a primary target of investigation in plant biology. …

Enzymatic activity of Xylaria digitata ; and, The cultivation of Penicillium pinophilium in nutrient salt solutions
… Digitata showed the presence of Diastase, Invertase, Cytase, Maltase, Emulsin and Erepsin. Oxidase, protease and Amidase were not found to be present.

Biochemical And Structural Characterization Of The Core Subunits Of Gpi Transamidase
… in Saccharomyces cerevisiae. Here we used Invertase as a reporter enzyme. Three GPI-T signal sequences were appended to the C-terminus of invertase and the amount of cell surfaced, GPI anchored invertase was measured. Overexpression of Gpi8, the catalytic subunit had little effect on GPI …

Nt-VIF - ein proteinogener Inhibitor der Vakuolären Invertasen in Tabak
Saure Invertasen haben im pflanzlichen Stoffwechsel eine große Bedeutung. Sie spielen eine wichtige Rolle bei der Regulation sink-Stärke und damit zusammenhängend der Assimilatverteilung in der Pflanze. Dar¬über hinaus beeinflussen sie die Zusammensetzung löslicher Zucker. Nachdem diese auch als …

Novel methods for on-site and cost-effective quantification of multiple targets using functional DNA and portable instruments
… magnetic beads, leading to the release of invertase-DNA strands. The strands then flows up with the liquid to an absorption pad pre-treated with sucrose, where the invertase linked on the strands converts sucrose into glucose in amounts proportional to the concentration of the target …

Continuous chromatographic biochemical reaction-separation
… and fructose in the presence of the enzyme invertase and the biochemIcal synthesis of dextran and fructose from sucrose in the presence of the enzyme dextransucrase were investigated. A dilute stream of the appropriate enzyme in deionised water was used as the eluent stream. The effect of …

The production of fructose from carbohydrate feedstocks
… were the inversion of sucrose using the enzyme invertase, by the use of hydrochloric acid and the use of the resin Amberlite IR118 in the H+ form. The preferred method on economic and purity considerations was by the use of the enzyme invertase. The continuous chromatographic separation of …

The Single drop drying of heat-sensitive materials
… 45%. Selected enzymes, viz. dextran sucrase and invertase, were also dried and their residual activities determined by High Performance Liquid Chromatography. The residual activity of dextran sucrase was rapidly reduced at temperatures above 65°C, and the residual activity of invertase reduced …

A comparison of leaf sucrose accumulation and regulation between plants of C.Plantagineum dried in the light and dark
… were examined, namely: hexokinase, acid invertase and aldolase. The amount of glucose, fructose and sucrose during the dehydration process in both light and dark treatments were also examined. Results obtained show a significant decrease in sucrose (9.8-fold decrease) when tissues of C. …

Development and optimisation of food products low in FODMAPs: an investigation of dietary fibres in low FODMAP products and the reduction of FODMAPs via bio-technological processes
… this challenge. Firstly, three enzymes (invertase, inulinase and α-galactosidase) were used to investigate the targeted degradation of fructans and GOS. Inulinase and invertase degrade both fructans and GOS, while α-galactosidase only degrades GOS. Inulinase was the most efficient in …

Modification of Vegetable Soybean Sugar Content via Gene Transformation
… 536.546) and Jack were transformed with yeast invertase (SUC 2) and $\alpha$-galactosidase (agl A) from Aspergillus niger under the control of the lectin promoter using particle bombardment. The transformation was not very successful. In some cultivars, no green clumps were obtained after 8 …
