Branched-dextran exo-1,2-alpha-glucosidase
Branched-dextran exo-1,2-alpha-glucosidase (EC 3.2.1.115, dextran 1,2-alpha-glucosidase, dextran alpha-1,2 debranching enzyme, 1,2-alpha-D-glucosyl-branched-dextran 2-glucohydrolase) is an enzyme with systematic name (1->2)-alpha-D-glucosyl-branched-dextran 2-glucohydrolase.[1][2] This enzyme catalyses the following chemical reaction
- Hydrolysis of (1->2)-alpha-D-glucosidic linkages at the branch points of dextrans and related polysaccharides, producing free D-glucose
