Phospho hexose isomerase
Glucose-6-phosphate isomerase (GPI), alternatively known as phosphoglucose isomerase/phosphoglucoisomerase (PGI) or phosphohexose isomerase (PHI), is an enzyme ( EC 5.3.1.9) that in humans is encoded by the GPI gene on chromosome 19. This gene encodes a member of the glucose phosphate … See more Functional GPI is a 64-kDa dimer composed of two identical monomers. The two monomers interact notably through the two protrusions in a hugging embrace. The active site of each monomer is formed by a cleft … See more The mechanism that GPI uses to interconvert glucose 6-phosphate and fructose 6-phosphate (aldose to ketose) consists of three … See more In some archaea and bacteria glucose-6-phosphate isomerase activity occurs via a bifunctional enzyme that also exhibits phosphomannose isomerase See more Human GPI is capable of inducing arthritis in mice with varied genetic backgrounds via intradermal injection. See more This gene belongs to the GPI family. The protein encoded by this gene is a dimeric enzyme that catalyzes the reversible isomerization of G6P and F6P. Since the reaction is … See more A deficiency of GPI is responsible for 4% of the hemolytic anemias due to glycolytic enzyme deficiencies.

This change from phosphoglucose to phosphofructose allows the eventual split of the sugar into two three-carbon molecules. Step 3. The third step is the phosphorylation of fructose-6-phosphate, catalyzed by the enzyme phosphofructokinase.
