Phosphomannose isomerase activity
WebSep 16, 2008 · Phosphomannose isomerase (PMI) plays a pivotal role in biosynthesis of GDP-mannose, an important precursor of many polysaccharides. We demonstrate in this study that Pseudomonas aeruginosa pslB encodes a protein with GDP-mannose pyrophosphorylase/PMI dual activities. The PMI activity is Co 2+-dependent and could be … WebPhosphomannose isomerase (PMI) catalyzes the reversible interconversion of mannose 6-phosphate and fructose 6-phosphate. Plant cells lacking this enzyme are incapable of surviving on synthetic medium containing mannose as a carbon source. Maize, wheat and barley plants, genetically modified to express the Escherichia coli manA gene (pmi) under …

An in silico analysis showed low PMI levels in human CRC tissues. We, therefore, investigated the effect of mannose alone or in combination with 5-FU in human CRC cell lines with different p53 and 5-FU resistance statuses.

WebNov 11, 2011 · Phosphomannose isomerase inhibitors improve N-glycosylation in selected phosphomannomutase-deficient fibroblasts Congenital disorders of glycosylation (CDG) are rare genetic disorders due to impaired glycosylation. Webisomerase (PGI), and glucose 6-phosphate dehydrogenase activity, decreases glycolysis, causes depletion of intracellular ATP and subsequent energy failure (Figure 1B). This effect was first observed in honeybees suffering from natural MPI insufficiency, and so it is known as “the honeybee effect.”18–20
