Function
function
Allosteric enzyme that catalyzes the rate-limiting step in glycogen catabolism, the phosphorolytic cleavage of glycogen to produce glucose-1-phosphate, and plays a central role in maintaining cellular and organismal glucose homeostasis.
Catalytic activity
- [(1->4)-alpha-D-glucosyl](n) + phosphate = [(1->4)-alpha-D-glucosyl](n-1) + alpha-D-glucose 1-phosphate
[(1→4)-α-D-glucosyl](n) RHEA-COMP:9584 + CHEBI:43474 = [(1→4)-α-D-glucosyl](n-1) RHEA-COMP:9586 + CHEBI:58601
