Phosphomannose isomerase function

WebJan 7, 2024 · Phosphoglucose isomerase (PGI) is one of the glycolytic enzymes and is a multifunctional enzyme that functions in glucose metabolism inside the cell while acting as a cytokine outside the cell ... WebAbstract. Phosphomannose isomerase (PMI) is a monomeric enzyme that converts fructose-6- P (Fru-6-P) and mannose-6-P (Man-6-P). It is the only known link between glucose catabolism and mannose activation for glycosylation. Man-6-P can also be produced directly via hexokinase from mannose.
