General description
Immobilized glucose isomerase produced from a selected strain of Streptomyces murinus.
Application
Glucose Isomerase from Streptomyces murinus has been used to isomerize xylose to xylulose during the production of dihydrogen from Xylose. It has also been used in the synthetic enzymatic pathway for dihydrogen production from sucrose, to catalyze isomerization of glucose to fructose.
Immobilized glucose isomerase produced from Streptomyces murinus was used for the isomerization of xylose. Glucose isomerase is used in the food industry to produce high-fructose corn syrup.
Biochem/physiol Actions
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.
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.
