- Glycogen phosphorylase
- Removes glucose residues from α-(1,4)-linkages within glycogen molecules
- Product of reaction: Glucose-1-phosphate.
- Converts glucose-1-phosphate to glucose-6-phosphate.
- Skeletal muscle: Glucose-6-phosphate is then metabolized by the glycolytic pathway.
- Phosphorylase b kinase
- Reactivates phosphorylase by phosphorylating it
- Debrancher enzyme
- Removes glucose from branch points (α-(1,6)-linkages) within glycogen
