Glucose Isomerase from Streptomyces murinus

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.
