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 -!- FUNCTION: Phosphorylase is an important allosteric enzyme in
CC carbohydrate metabolism. Enzymes from different sources differ in their
CC regulatory mechanisms and in their natural substrates. However, all
CC known phosphorylases share catalytic and structural properties.
CC {ECO:0000256|ARBA:ARBA00025174}.
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|ARBA:ARBA00001275,
CC 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}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
