Disease

PYGL_HUMAN Defects in PYGL are the cause of glycogen storage disease type 6 (GSD6) [MIM:232700. A metabolic disorder characterized by mild to moderate hypoglycemia, mild ketosis, growth retardation, and prominent hepatomegaly. Heart and skeletal muscle are not affected.^[1]

Function

PYGL_HUMAN Phosphorylase is an important allosteric enzyme in carbohydrate metabolism. Enzymes from different sources differ in their regulatory mechanisms and in their natural substrates. However, all known phosphorylases share catalytic and structural properties.
