Phosphoglucose Isomerase, sourced from rabbit muscle, plays a crucial role in glycolysis and gluconeogenesis pathways. It catalyzes the interconversion of glucose-6-phosphate and fructose-6-phosphate, a vital step in energy production and carbohydrate metabolism. This enzyme is widely utilized in biochemical research to study metabolic processes and enzyme kinetics. It is also employed in diagnostic assays to measure glucose metabolism in clinical settings. Additionally, it serves as a tool in industrial biotechnology for the production of fructose-based sweeteners and other carbohydrate derivatives. Its stability and specificity make it a valuable component in enzymatic studies and biotechnological applications.
