Enzymes for Research, Diagnostic and Industrial Use

Cellobiohydrolase II from Microbial, Recombinant

Cat No.
NATE-1022
Description
Cellulose 1,4-beta-cellobiosidase (non-reducing end) is an enzyme with system name 4-beta-D-glucan cellobiohydrolase (non-reducing end). This enzyme catalyses the following chemical reaction:Hydrolysis of (1->4)-beta-D-glucosidic linkages in cellulose and cellotetraose, releasing [cellobiose] from the non-reducing ends of the chains.
