Enzyme Information

3.2.1.41
Pullulanase.
based on mapping to UniProt C0SPA0
Hydrolysis of (1->6)-alpha-D-glucosidic linkages in pullulan, amylopectin and glycogen, and in the alpha- and beta-limit dextrins of amylopectin and glycogen.
-!- Different from EC 3.2.1.142 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 alpha- (1->6)-linkage. -!- Formerly EC 3.2.1.69.
