Mannose-6-Phosphate Isomerase is an enzyme that plays a crucial role in carbohydrate metabolism. It catalyzes the conversion of mannose-6-phosphate to fructose-6-phosphate, which is an important step in the synthesis of glycoproteins and glycolipids. This enzyme is essential for proper cellular function and energy production. Deficiencies in Mannose-6-Phosphate Isomerase can lead to various metabolic disorders, affecting the body's ability to process sugars. Such deficiencies may result in symptoms like developmental delays and immune system issues. Understanding this enzyme is vital for research into related genetic conditions and potential treatments.
