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.

Actions biochimiques/physiologiques

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.

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 7.4 at 25 °C.

Forme physique

Essentially sulfate-free powder containing citrate buffer salts

Glucose is a critical metabolic fuel in most mammals although many foodstuffs also contain high levels of the monosaccharides, galactose and fructose. The aims of this work were to determine the insulin response to challenges of these sugars (experiment 1)

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

Nitrogen (N) limitation reduces leaf growth and photosynthetic rates of maize (Zea mays), and constrains photosynthate translocation to developing ears. Additionally, the period from about 1 week before to 2 weeks after silking is critical for establishing the reproductive sink

Phosphoglucose isomerase (PGI) is a cytosolic glycolytic enzyme that also functions as an extracellular cytokine (neuroleukin/autocrine motility factor (AMF)/maturation factor). Contrary to mammalian PGI, bacterial PGI was not internalized by the PGI/AMF receptor (gp78/AMF-R) and neither bacterial nor yeast PGI

Glutamine synthetase (GS) and glucose-6-phosphate isomerase (GPI) were identified as novel adhesive moonlighting proteins of Lactobacillus crispatus ST1. Both proteins were bound onto the bacterial surface at acidic pHs, whereas a suspension of the cells to pH 8 caused their
