Descripción general
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.[1] Optimum pH is found to be between 9-10 and the isoelectric point is 4.2.
Aplicación
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 Sigma has been used in the determination of fructose 6-phosphate in a mutant strain of Rhizobium meliloti.[2]
Acciones bioquímicas o fisiológicas
Phosphoglucose Isomerase fuctions as an isomerase, neuroleukin, autocrine motility factor, and a differentiation and maturation mediator.
Definición de unidad
One unit will convert 1.0 μmole of D-fructose 6-phosphate to D-glucose 6-phosphate per min at pH 9.0 at 30 °C.

A mutant strain of complex phenotype was selected in Rhizobium meliloti after nitrosoguanidine mutagenesis. It failed to grow on mannitol, sorbitol, fructose, mannose, ribose, arabitol, or xylose, but grew on glucose, maltose, gluconate, L-arabinose, and many other carbohydrates. Assay showed

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

Little is known of intron sequences' variation in cases where eukaryotic gene coding regions undergo strong balancing selection. Phosphoglucose isomerase, PGI, of Colias butterflies offers such a case. Its 11 introns include many point mutations, insertions, and deletions. This variation
