Amylo-α-1,6-glucosidase (EC3.2.1.33, amylo-1,6-glucosidase, dextrin 6-α-D-glucosidase, amylopectin 1,6-glucosidase, dextrin-1,6-glucosidase, glycogen phosphorylase-limit dextrin α-1,6-glucohydrolase) is an enzyme with systematic nameglycogen phosphorylase-limit dextrin 6-α-glucohydrolase.[1][2][3] It catalyses the hydrolysis of unsubstituted glucose units in glycogen linked by α(1→6) bonds to α(1→4)glucose chains.
