Description
Phosphoglucose Isomerase (PGI) is an enzyme crucial for the interconversion of D-glucose 6-phosphate and D-fructose 6-phosphate. PGI is responsible for the second step of glycolysis and is involved in glucogenesis. It is highly conserved in bacteria and eukaryotes.

Applications
Phosphoglucose Isomerase (PGI) is an enzyme crucial for the interconversion of D-glucose 6-phosphate and D-fructose 6-phosphate. PGI is responsible for the second step of glycolysis and is involved in glucogenesis. It is highly conserved in bacteria and eukaryotes. It is used in sugar assays to convert fructose to glucose. This product is from Bacillus stearothermophilus. The enzyme from Creative Enzymes has been used in the determination of fructose 6-phosphate in a mutant strain of Rhizobium meliloti.
Product Overview
The enzyme is part of the glycolytic pathway. Also, it is important in the industrial production of fructose 1,6-diphosphate (FDP) from glucose. The molecular mass is found to be approximately 189 kDa and it consists of four subunits, each with a molecular mass of approximately 50 kDa. Optimum pH is found to be between 9-10 and the isoelectric point is 4.2.
