General Information

Term

amylo-alpha-1,6-glucosidase activity

ID (Ontology)

GO:0004135 (Gene Ontology)

Definition

Catalysis of the hydrolysis of (1->6)-alpha-D-glucosidic branch linkages in glycogen phosphorylase limit dextrin. Limit dextrin is the highly branched core that remains after exhaustive treatment of glycogen with glycogen phosphorylase. It is formed because these enzymes cannot hydrolyze the (1->6) glycosidic linkages present.[ EC:3 ]

Also Known As
