Glucan 1,3-beta-glucosidase
Glucan 1,3-beta-glucosidase (EC 3.2.1.58, exo-1,3-beta-glucosidase, beta-1,3-glucan exo-hydrolase, exo (1->3)-glucanohydrolase, 1,3-beta-glucan glucohydrolase) is an enzyme with systematic name 3-beta-D-glucan glucohydrolase.[1][2] This enzyme catalyses the following chemical reaction
- Successive hydrolysis of beta-D-glucose units from the non-reducing ends of (1->3)-beta-D-glucans, releasing alpha-glucose
