Structured Summary
Abstract
An enzyme that hydrolyzes 1,6-alpha-glucosidic branch linkages in glycogen, amylopectin, and their beta-limit dextrins. It is distinguished from pullulanase (EC 3.2.1.41) by its inability to attack pullulan and by the feeble action of alpha-limit dextrins. It is distinguished from amylopectin 6-glucanohydrolase (EC 3.2.1.69) by its action on glycogen. With EC 3.2.1.69, it produces the activity called debranching enzyme. EC 3.2.1.68.
