Description générale
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.
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. 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.
Actions biochimiques/physiologiques
Phosphoglucose Isomerase fuctions as an isomerase, neuroleukin, autocrine motility factor, and a differentiation and maturation mediator.
Définition de l'unité
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

Structural biology and structural genomics projects routinely rely on recombinantly expressed proteins, but many proteins and complexes are difficult to obtain by this approach. We investigated native source proteins for high-throughput protein crystallography applications. The Escherichia coli proteome was fractionated

In the Gran Chaco region the reinfestation by Triatoma infestans remains a major problem for control of Chagas disease. Trypanosoma cruzi the agent of the illness presents a broad genetic intraspecific variability which is poorly documented in the Bolivian Gran

The current persistence of Triatoma infestans (one of the main vectors of Chagas disease) in some domestic areas could be related to re-colonization by wild populations which are increasingly reported. However, the infection rate and the genetic characterization of the
