Limit dextrinase
Limit dextrinase (EC 3.2.1.142, R-enzyme, amylopectin-1,6-glucosidase, dextrin alpha-1,6-glucanohydrolase) is an enzyme with systematic name dextrin 6-alpha-glucanohydrolase.[1][2] This enzyme catalyses the hydrolysis of (1->6)-alpha-D-glucosidic linkages in alpha- and beta-limits dextrins of amylopectin and glycogen,in amylopectin and pullulan.
