Phosphoglucose isomerase glycolysis
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 isomerase protein family. The encoded protein has been identified as a moonli… WebPhosphoglucomutase ( EC 5.4.2.2) is an enzyme that transfers a phosphate group on an α-D- glucose monomer from the 1 to the 6 position in the forward direction or the 6 to the 1 position in the reverse direction.
