Isomerase, any one of a class of enzymes that catalyze reactions involving a structural rearrangement of a molecule. Alanine racemase, for example, catalyzes the conversion of L-alanine into its isomeric (mirror-image) form, D-alanine. An isomerase called mutarotase catalyzes the conversion of α-d-glucose into β-d-glucose. cf. ligase, lyase. patented. Glucose Isomerase despite its diverse uses as sweetner in the carbonated beverage industries has never really received much attention in terms of local production and utilization. It is however on the basis of adding value to the production of glucose isomerase from locally available raw material that the research was focused at achieving.

Glucose phosphate isomerase (GPI) deficiency is an inherited disorder that affects red blood cells, which carry oxygen to the body's tissues. People with this disorder have a condition known as chronic hemolytic anemia, in which red blood cells are broken down (undergo hemolysis) prematurely, resulting in a shortage of red blood cells (anemia).   In the cytoplasm, catalyzes the conversion of glucosephosphate to fructosephosphate, the second step in glycolysis, and the reverse reaction during gluconeogenesis (PubMed). Besides it's role as a glycolytic enzyme, also acts as a secreted cytokine: acts as an angiogenic factor (AMF) that stimulates endothelial cell motility (PubMed).

Abstract. A break-through in the development of sweet corn syrups occurred when glucose isomerase was introduced in This enzyme isomerizes glucose to the sweeter sugar fructose, and the resulting product is competitive with sucrose with respect to Studies on glucose isomerase.

book. Cell-free glucose isomerase, obtained from mycelia heat-treated in the presence of mM Co2+, showed a fold increase in specific activity over enzyme obtained from untreated mycelia. The optimum pH and temperature for the glucose isomerase were 7 to 8 and 80 degrees C, respectively.

Process engineering considerations important in the exploitation of enzyme-catalyzed reactions for large-scale production of desired products are illustrated in the context of a case study of glucose isomerase technology. The state of the art of glucose isomerase processing as revealed by journal and patent literature is reviewed and assessed.

Here, we explore the effect of external electric fields on the crystallization process of Glucose Isomerase (GI) from Streptomyces rubiginosus, an enzyme used industrially to convert glucose to fructose in the manufacturing of high-fructose corn take advantage of the microbatch method [38,39] that allows for low protein consumption, and combine it with a unique design of.

D-Glucose/xylose isomerase (D-xylose ketol isomerase; EC ), commonly referred to as glucose isomerase (GI), is one of the three highest tonnage value enzymes, amylase and.

A glucose isomerase which reversibly catalyzes the reaction between d-glucose and d-fructose was demonstrated in the cell-free extracts of a strain of Streptomyces sp. isolated from soil. The enzyme was produced when the strain was grown in the medium containing xylan or xylan-containing material such as wheat bran.

Glucose isomerase (GI, EC ), also known as xylose isomerase, D-xylose isomerase, D-xylose keto isomerase, and D-xylose ketol-isomerase, is an isomerase that isomerizes aldose, such as D-xylose, D-glucose, D-ribose, etc., to the corresponding systematic name of this enzyme class is D-xylose aldose-ketose-isomerase.

Glucose isomerase (also known as xylose isomerase, EC ) is an example of the highly successful application of enzyme biotechnology to an industrial process that has no commercially viable route through conventional chemistry. Chemical isomerization of glucose to fructose at high pH and high temperature leads to undesirable side products.

This book brings together all the relevant information on themanufacture and use of glucose syrups. Drawing on fortyyears’ experience in the international glucose industry, theauthor provides a valuable reference for all those involved in theprocessing and buying of these syrups, and for scientists involvedin the manufacture of a full range.Besides the amylolytic enzymes, there must also be a glucose-isomerase enzyme in action, and it must be its effect which results in the appearance of fructose.
