PYGM_HUMAN Defects in PYGM are the cause of glycogen storage disease type 5 (GSD5) [MIM:232600; also known as McArdle disease. GSD5 is a metabolic disorder resulting in myopathy characterized by exercise intolerance, cramps, muscle weakness and recurrent myoglobinuria.[1][2][3][4][5][6][7][8][9][10][11][12][13]
Function
PYGM_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.
