Reaction: Hydrolysis of (1→2)-α-D-glucosidic linkages at the branch points of dextrans and related polysaccharides, producing free D-glucose
Other name(s): dextran 1,2-α-glucosidase; dextran α-1,2-debranching enzyme; 1,2-α-D-glucosyl-branched-dextran 2-glucohydrolase
Systematic name: (1→2)-α-D-glucosyl-branched-dextran 2-glucohydrolase
Comments: Has a much lower activity with kojibiose and kojitriose.
