Mannose-6 phosphate isomerase (MPI), alternately phosphomannose isomerase (PMI) (EC 5.3.1.8) is an enzyme which facilitates the interconversion of fructose 6-phosphate (F6P) and mannose-6-phosphate (M6P). Mannose-6-phosphate isomerase may also enable the synthesis of GDP-mannose in … See more MPI must convert an aldose (mannose) to a ketose (fructose), in addition to opening and closing the rings for these sugars. In humans a mechanism has been suggested which involves a hydrogen transfer between C1 … See more MPI is composed of 440 amino acid residues, with one active site and one zinc ion (Zn ) ligand.

WebPatients with congenital disorder of glycosylation (CDG), type Ib (MPI-CDG or CDG-Ib) have mutations in phosphomannose isomerase (MPI) that impair glycosylation and lead to stunted growth, liver dysfunction, coagulopathy, hypoglycemia, and intestinal abnormalities. Mannose supplements correct hypogl … WebSince MPI could convert mannose-6-phosphate to fructose-6-phophate and then use fructose-6-phophate for glycolysis ( 34 ), these findings suggest that mannose can suppress glycolysis in cells expressing low amounts of MPI by competing hexokinase (HK) with glucose; whereas in cells expressing high amounts of MPI, mannose-6-phosphate could …
