The mechanism that GPI uses to interconvert glucose 6-phosphate and fructose 6-phosphate (aldose to ketose) consists of three major steps: opening the glucose ring, isomerizing glucose into fructose through an enediol intermediate, and closing the fructose ring. Isomerization of glucose Compound C00668 at … See more 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 See more Functional GPI is a 64-kDa dimer composed of two identical monomers. The two monomers interact notably through the two … See more In some archaea and bacteria glucose-6-phosphate isomerase activity occurs via a bifunctional enzyme that also exhibits phosphomannose isomerase (PMI) activity. Though not … 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 reversible, its direction is determined by G6P and F6P concentrations. See more A deficiency of GPI is responsible for 4% of the hemolytic anemias due to glycolytic enzyme deficiencies. Several cases of GPI deficiency have recently been identified. Elevated serum GPI levels have been used as a prognostic biomarker for colorectal, breast See more • Fructose-1-phosphate-aldolase enzyme, which converts fructose to glucose See more WebON THE MECHANISM ISOMERASE AND OF ACTION OF PHOSPHOGLUCOSE PHOSPHOMANNOSE ISOMERASE BY YALE J.
