MetaCyc Reaction: 3.2.1.142

Superclasses: Reactions Classified By Conversion Type Simple Reactions Chemical Reactions
Reactions Classified By Substrate Small-Molecule Reactions

EC Number: 3.2.1.142

The reaction direction shown, that is, A + B ↔ C + D versus C + D ↔ A + B, is in accordance with the Enzyme Commission system.

Mass balance status: Undetermined; a substrate lacks a chemical formula

Enzyme Commission Primary Name: limit dextrinase

Enzyme Commission Synonyms: R-enzyme, amylopectin-1,6-glucosidase, dextrin α-1,6-glucanohydrolase

Enzyme Commission Summary:
This enzyme catalyzes hydrolysis of (1->6)-α-D-glucosidic linkages in α- and β-limit dextrins of amylopectin and glycogen, and in amylopectin and pullulan.

Plant enzymes with little or no action on glycogen.

Action on amylopectin is incomplete, but action on α-limit dextrins is complete.

Maltose is the smallest sugar it can release from an α-(1->6)-linkage.
