How Is Isomerase Used?

An isomerase known as mutarotase catalyzes the conversion of α-d-glucose into β-d-glucose. ... Isomerases are used in many applications. In metabolic engineering, xylose isomerase

xylose isomerase
Active site and mechanism

Xylose isomerase has a structure that is based on eight alpha/beta barrels that create an active site holding two divalent magnesium ions. Xylose isomerase enzymes exhibit a TIM barrel fold with the active site in the centre of the barrel and a tetrameric quaternary structure.

(EC 5.3. 1.5) has been traditionally used to convert glucose to fructose in the syrup industry.

What is the role of isomerase enzyme in glycolysis?

Glucose isomerase (otherwise called xylose isomerase) catalyzes the transformation of D-xylose and D-glucose to D-xylulose and D-fructose. Similar to most sugar isomerases, glucose isomerase catalyzes the interconversion of aldoses and ketoses.

Why is glucose isomerase used?

Glucose(xylose) isomerase catalyzes the reversible isomerization of glucose to fructose and that of xylose to xylulose. It is an important enzyme used in the industrial production of high-fructose corn syrup (HFCS) (3).
