Phosphoglucose isomerase glycolysis

WebApr 30, 2002 · Phosphoglucose isomerase (PGI; EC 5.3.1.9) is a cytosolic glycolytic enzyme that catalyzes the reversible isomerization of d -glucose 6-phosphate (G6P) to d -fructose 6-phosphate (F6P). WebDec 30, 2024 · Glucose-6-Phosphate is converted to Fructose-6-Phosphate by phosphoglucose isomerase. As the name implies, the isomerase simply rearranges the existing atoms within the G6P to make the F6P without removal or addition of any atoms. 3. Fructose-6-Phosphate is phosphorylated by phosphofructokinase (PFK) to Fructose- 1,6 …
