EC 18.104.22.168 - Pullulanase
IntEnz Enzyme Nomenclature
bacterial debranching enzyme
limit dextrinase [incorrect]
- Hydrolysis of (1→6)-α-D-glucosidic linkages in pullulan, amylopectin and glycogen, and in the α- and β-limit dextrins of amylopectin and glycogen.
Different from EC 22.214.171.124 (limit dextrinase) in its action on glycogen, and its rate of hydrolysis of limit dextrins. Its action on amylopectin is complete. Maltose is the smallest sugar that it can release from an α-(1→6)-linkage.
