Phosphoglucoisomerase function
WebDec 10, 2024 · Function Phosphoglucose isomerase (PGI) or glucose-6-phosphate isomerase catalyzes the conversion of glucose-6-phosphate to fructose-6-phosphate [1]. … WebIt transfers a phosphate from ATP to glucose, forming glucose-6-phosphate. Daniel Koshland realized, a decade before the structure was known, that this chemical reaction must be shielded from water, to keep the phosphate from being simply cleaved off of ATP by a water molecule.
