Application

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 . Product 9544 is type XI and is from rabbit muscle. It is useful in enzyme systems requiring low sulfate.

Biochem/physiol Actions

Phosphoglucose Isomerase fuctions as an isomerase, neuroleukin, autocrine motility factor, and a differentiation and maturation mediator . It is responsible for the photosynthetic reduction of carbon.

Unit Definition

One unit will convert 1.0 μmole of D-fructose 6-phosphate to D-glucose 6-phosphate per min at pH 7.4 at 25 °C.

Physical form

Essentially sulfate-free powder containing citrate buffer salts

The multifunctional protein phosphoglucose isomerase, also known as neuroleukin, autocrine motility factor, and differentiation and maturation mediator, has different roles inside and outside the cell. In the cytoplasm, it catalyzes the second step in glycolysis. Outside the cell, it serves

Glycolytic enzymes are cytosolic proteins, but they also play important extracellular roles in cell-cell communication and infection. We used Saccharomyces cerevisiae to analyze the secretory pathway of some of these enzymes, including enolase, phosphoglucose isomerase, triose phosphate isomerase, and fructose

The marine copepod Tigriopus californicus lives in intertidal rock pools along the Pacific coast, where it exhibits strong, temporally stable population genetic structure. Previous allozyme surveys have found high frequency private alleles among neighboring subpopulations, indicating that there is limited
