Phosphomannose isomerase (Escherichia coli)

CAS: 9023-88-5 

mannose-6-phosphate isomerase; D-mannose-6-phosphate aldose-ketose-isomerase

In 3.2 M ammonium sulphate.

> 4 years at 4oC.

Specific activity:
~ 100 U/mg (25oC, pH 7.6 on mannose 6-phosphate).

Unit definition:
One Unit of phosphomannose isomerase activity is defined as the amount of enzyme required to release one µmole of fructose 6-phosphate from mannose 6-phosphate (3.14 mM) per minute in the presence of NAD+ at pH 7.6 and 25oC.

Catalyses the reaction:
D-Mannose 6-phosphate = D-fructose 6-phosphate.

Applications for the measurement of D-mannose in carbohydrate research and in the food and feeds, fermentation, wine, beverage and dairy industries.
