CC -!- FUNCTION: Allosteric enzyme that catalyzes the rate-limiting step in
CC glycogen catabolism, the phosphorolytic cleavage of glycogen to produce
CC glucose-1-phosphate, and plays a central role in maintaining cellular
CC and organismal glucose homeostasis. {ECO:0000256|RuleBase:RU000587}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=[(1->4)-alpha-D-glucosyl](n) + phosphate = [(1->4)-alpha-D-
CC glucosyl](n-1) + alpha-D-glucose 1-phosphate; Xref=Rhea:RHEA:41732,
CC Rhea:RHEA-COMP:9584, Rhea:RHEA-COMP:9586, ChEBI:CHEBI:15444,
CC ChEBI:CHEBI:43474, ChEBI:CHEBI:58601; EC=2.4.1.1;
CC Evidence={ECO:0000256|RuleBase:RU000587};
CC -!- COFACTOR:
CC Name=pyridoxal 5'-phosphate; Xref=ChEBI:CHEBI:597326;
CC Evidence={ECO:0000256|ARBA:ARBA00001933,
CC ECO:0000256|RuleBase:RU000587};
CC -!- SIMILARITY: Belongs to the glycogen phosphorylase family.
CC {ECO:0000256|ARBA:ARBA00006047, ECO:0000256|RuleBase:RU000587}.
