Five general types of cellulases based on the type of reaction catalyzed: • Endocellulases (EC 3.2.1.4) randomly cleave internal bonds at amorphous sites that create new chain ends. • Exocellulases or cellobiohydrolases (EC 3.2.1.91) cleave two to four units from the ends of the exposed chains produced by endocellulase, resulting in tetrasaccharides or disaccharides, such as cellobiose. Exocellulases are further classified into type I, that work proc… device manager windows 10 indir
