WebPhosphomannose-isomerase (PMI) deficiency is a (cytosolic) defect in the first step of the biosynthesis of the nucleotide sugar GDP-Man. The substrate of the enzyme, fructose 6-phosphate, does not accumulate since it is an intermediate of the glycolytic pathway. The blood biochemical abnormalities are indistinguishable from those found in PMM2-CDG. 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. WebThree consecutive enzymes, namely, phosphomannose isomerase (PMI), phosphomannose mutase (PMM), and GDP-mannose phosphorylase (GMPP), are required for GDP-Man biosynthesis. Thus, PMI is of prime importance in cell wall biosynthesis and also has an active role in sugar metabolism. Here, we investigated the functional role of PMI in A. … dog ear and tail cropping
