Isomerase plays a role in human disease. Deficiencies of this enzyme can cause disorders in humans. Phosphohexose Isomerase Deficiency (PHI) is also known as phosphoglucose isomerase deficiency or Glucose-6-phosphate isomerase deficiency, and is a hereditary enzyme deficiency. PHI is the second most frequent erthoenzyopathy in glycolysis besides pyruvate kinase deficiency, … WebThe first reaction of glycolysis is the ATP-dependent phosphorylation of glucose to form glucose-6-phosphate This reaction is catalyzed by tissue-specific isoenzymes known as HEXOKINASES Bound Mg2+ facilitates this process by stabilizing the negative charge in the transition state. This process uses the energy of ATP
