additional information distinguished from alpha-dextrin endo-1,6-alpha-glucosidase, EC 3.2.1.41, by the inability of isoamylase to attack pullulan, and by limited action on alpha-limit dextrins, action on glycogen however is complete in contrast to limited action by alpha-dextrin glucanohydrolase, 1,6-linkage hydrolysed only at branch point Pseudomonas amyloderamosa ?
