WebSep 3, 2012 · The selection system uses theEscherichia coli pmi gene that encodes phosphomannose isomerase (PMI). Transgenic plants carrying thepmi gene can detoxify … WebMPI encodes phosphomannose isomerase, which interconverts fructose 6-phosphate and mannose 6-phosphate (Man-6-P), used for glycoconjugate biosynthesis. MPI mutations in humans impair protein glycosylation causing congenital disorder of glycosylation Ib (CDG-Ib), but oral mannose supplements normalize glycosylation. To establish a mannose …
WebThis reaction is catalyzed by phosphoglucose isomerase (or glucose-6-phosphate isomerase), and there exists a very similar enzyme, phosphomannose isomerase (or mannose-6-phosphate isomerase), which transforms mannose-6-℗ (an epimer of glucose-6-℗, which differs from it only by the configuration of the hydroxyl on carbon 2: see fig. 4-5) …

Transgenic plants carrying the pmi gene can detoxify mannose-6-phosphate by conversion to fructose-6-phosphate, an intermediate of glycolysis, via the PMI activity.
WebSep 17, 2024 · We hypothesized that leukemia cells use sugars other than glucose as a glycolytic energy source. Our experiments revealed that these cells metabolize mannose using phosphomannose isomerase (PMI), and that mannose is an energy source for glycolysis and oxidative phosphorylation (OXPHOS).
