#XL - Q Biochemistry

Phosphohexose isomerase is one of the enzyme of glycolysis which catalyzes Glucose 6-phosphate to Fructose 6-phosphate, enzyme bind with the hexose in their active site by opening the structure. The ring opening and closing reactions are catalyzed by an active-site present amino acid such as
