Description
In enzymology, a xylose isomerase (EC 5.3.1.5) is an enzyme that catalyzes the interconversion of D-xylose and D-xylulose. This enzyme belongs to the family of isomerases, specifically those intramolecular oxidoreductases interconverting aldoses and ketoses. The isomerase has now been observed in nearly a hundred species of bacteria. Xylose-isomerases are also commonly called glucose-isomerases due to their extensive use in the industry to produce high fructose corn syrup from glucose.
Abbr
Glucose Isomerase, Native (Streptomyces murinus)
Source
Streptomyces murinus
Applications
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.
