WebFeb 5, 2024 · Summary. Phosphomannose isomerase catalyzes the interconversion of fructose-6-phosphate and mannose-6-phosphate and plays a critical role in maintaining the supply of D-mannose derivatives, which are required for most glycosylation reactions. Mutations in the MPI gene were found in patients with carbohydrate-deficient glycoprotein … WebBackground: Some glycosylation-deficient patients do not make enough mannose-1-P from mannose-6-P. Preventing mannose-6-P catabolism might improve glycosylation in cells and patients.Results: Inhibitors of mannose-6-P catabolism direct more mannose toward N-glycosylation in many cell types.Conclusion: Increasing exogenous mannose and blocking …
WebMay 13, 2024 · Recent studies have found that Zn 2+ is crucial for mannose phosphate isomerase (PMI) to exert enzymatic activity, and when ZIP10, a transporter of Zn 2+, is knocked down, it causes the inactivation of MPI and makes tumor cells become mannose sensitive.

Furthermore, we report here the phosphomannose isomerase substrate D-mannose 6-phosphate as the best inhibitor of E. coli D-sorbitol-6-phosphate 2-dehydrogenase yet ...
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 and C2, mediated by Tyr278, and the movement of a proton from O1 and O2 mediated by the associated Zn ion. The ring opening step may be catalyzed by His99 an…
