IUBMB Enzyme Nomenclature


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 enzymel 1,2-α-D-glucosyl-branched-dextran 2-glucohydrolase

Systematic name: (1→2)-α-D-glucosyl-branched-dextran 2-glucohydrolase

Comments: Does not hydrolyse disaccharides or oligosaccharides containing linear 1,2-α-glucosidic linkages.
