PYGM 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. Belongs to the glycogen phosphorylase family. 2 alternatively spliced human isoforms have been reported. Note: This description may include information from UniProtKB.
