EC 3.2.1.115

Accepted name: branched-dextran exo-1,2-α-glucosidase

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.
