Term Information [More information on phosphorylase activity]

Accession
GO:0004645
Name
phosphorylase activity
Ontology
molecular_function
Synonyms
1,4-alpha-D-glucan:phosphate alpha-D-glucosyltransferase activity, 1,4-alpha-glucan phosphorylase activity, polyphosphorylase activity, amylopectin phosphorylase, amylophosphorylase activity, glucan phosphorylase, glucosan phosphorylase, granulose phosphorylase, muscle phosphorylase, muscle phosphorylase a and b activity, myophosphorylase, potato phosphorylase, starch phosphorylase, alpha-glucan phosphorylase
Definition
Catalysis of the reaction: 1,4-alpha-D-glucosyl(n) + phosphate = 1,4-alpha-D-glucosyl(n-1) + alpha-D-glucose 1-phosphate. The name should be qualified in each instance by adding the name of the natural substrate, e.g. maltodextrin phosphorylase, starch phosphorylase, glycogen phosphorylase. Source: EC:2.4.1.1
