Glycogen Debranching Enzyme Functions and Mechanism

The video tutorial explains the mechanisms of glycogen catabolism, focusing on the roles of glycogen phosphorylase and glycogen debranching enzyme. Glycogen phosphorylase removes terminal glucose units as glucose-1-phosphate, while the debranching enzyme, a hydrolase, uses water to release simple glucose. The debranching enzyme has transferase and glucosidase activities, crucial for processing branches with four glucose units. The tutorial also covers the molecular mechanism of the debranching enzyme, highlighting the differences between the two enzymes in terms of their products and processes.
