IntEnz Enzyme Nomenclature
EC 3.2.1.142

Names

Accepted name:
limit dextrinase
Other names:
R-enzyme
amylopectin-1,6-glucosidase
dextrin α-1,6-glucanohydrolase
Systematic name:
dextrin α-6-glucanohydrolase

Reaction

Comments:

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.
