Cellulose 1,4-β-cellobiosidase (reducing end)
Cellulose 1,4-β-cellobiosidase (reducing end) (EC 3.2.1.176, CelS, CelSS, endoglucanase SS, cellulase SS, cellobiohydrolase CelS, Cel48A) is an enzyme with systematic name 4-beta-D-glucan cellobiohydrolase (reducing end).[1][2] This enzyme catalyses the following chemical reaction
- Hydrolysis of (1->4)-beta-D-glucosidic linkages in cellulose and similar substrates, releasing cellobiose from the reducing ends of the chains.
