Entry
EC 3.2.1.142                Enzyme                                 

Name
limit dextrinase;
R-enzyme;
amylopectin-1,6-glucosidase;
dextrin alpha-1,6-glucanohydrolase
Class
Hydrolases;
Glycosylases;
Glycosidases, i.e. enzymes that hydrolyse O- and S-glycosyl compounds
BRITE hierarchy
Sysname
dextrin 6-alpha-glucanohydrolase
Reaction(IUBMB)
Hydrolysis of (1->6)-alpha-D-glucosidic linkages in alpha- and beta-limit dextrins of amylopectin and glycogen, and in amylopectin and pullulan
Comment
Plant enzymes with little or no action on glycogen. Action on amylopectin is incomplete, but action on alpha-limit dextrins is complete. Maltose is the smallest sugar it can release from an alpha-(1->6)-linkage.
