Branched-dextran exo-1,2-alpha-glucosidase explained

Branched-dextran exo-1,2-α-glucosidase
Ec Number:	3.2.1.115
Cas Number:	72840-94-9

Branched-dextran exo-1,2-α-glucosidase (dextran 1,2-α-glucosidase, dextran α-1,2 debranching enzyme, 1,2-α-D-glucosyl-branched-dextran 2-glucohydrolase) is an enzyme with systematic name (1→2)-α-D-glucosyl-branched-dextran 2-glucohydrolase.^{[1] [2]} It catalyses the hydrolysis of (1→2)-α-D-glucosidic linkages at the branch points of dextrans and related polysaccharides, producing free D-glucose.

This enzyme does not hydrolyse disaccharides or oligosaccharides containing linear 1,2-α-glucosidic linkages.
