일반 설명

Immobilized glucose isomerase produced from a selected strain of Streptomyces murinus.

애플리케이션

Glucose Isomerase from Streptomyces murinus has been used to isomerize xylose to xylulose during the production of dihydrogen from Xylose.[1][2] It has also been used in the synthetic enzymatic pathway for dihydrogen production from sucrose, to catalyze isomerization of glucose to fructose.[2]
Immobilized glucose isomerase produced from Streptomyces murinus was used for the isomerization of xylose.[3] Glucose isomerase is used in the food industry to produce high-fructose corn syrup[4].

생화학적/생리학적 작용

Few anaerobic bacteria, fungi and plants express an intracellular metalloenzyme called D-xylose isomerase (XI). Most bacteria use the enzyme D-xylose isomerase to transform D-xylose to D-xylulose. D-Xylose isomerase (XI) converts the aldo-sugars xylose and glucose to their keto analogs xylulose and fructose.[5]
Glucose isomerase has wide variety of industrial applications such as producing high-fructose corn syrup (HFCS) and production of ethanol from hemicelluloses. In addition, it also facilitates the study of structure-function relationships by advanced biochemical and genetic engineering techniques.[6]

In this paper, we demonstrate the feasibility of using in situ Dynamic Light Scattering (DLS) to monitor counter-diffusion crystallization experiments in capillaries. Firstly, we have validated the quality of the DLS signal in thin capillaries, which is comparable to that

Protein crystals form in supersaturated solutions via a nucleation and growth mechanism. The amyloid fibrils of denatured proteins also form via a nucleation and growth mechanism. This similarity suggests that, although protein crystals and amyloid fibrils are distinct in their

The heterologous expression of a highly functional xylose isomerase pathway in Saccharomyces cerevisiae would have significant advantages for ethanol yield, since the pathway bypasses cofactor requirements found in the traditionally used oxidoreductase pathways. However, nearly all reported xylose isomerase-based pathways

  1. Is G4166 an immobilized enzyme? If it is, what support is it immobilized on?

    1 답변
    1. This is a Novozyme product, Sweetzyme® IT Extra, which is an immobilized enzyme. It is glutaraldehyde crosslinked on polyethyleneimine, and intended to be used in a continuous fixed bed process (converting high dextrose syrup to high fructose syrup).
