ENZYME entry: EC

Accepted Name
Alternative Name(s)
Alpha-dextrin endo-1,6-alpha-glucosidase.
Amylopectin 6-glucanohydrolase.
Debranching enzyme.
Limit dextrinase.
Pullulan 6-glucanohydrolase.
Reaction catalysed
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 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
