Mode of actions
- (Fungus) "The biological conversion of cellulose to glucose generally requires three types of hydrolytic enzymes: (1) Endoglucanases which cut internal beta-1,4-glucosidic bonds; (2) Exocellobiohydrolases that cut the dissaccharide cellobiose from the non-reducing end of the cellulose polymer chain; (3) Beta-1,4-glucosidases which hydrolyze the cellobiose and other short cello-oligosaccharides to glucose."[1]

Endoglucanse
- e.g. T. reesei EG-1; GH7; CBM1
Exoglucanase
- Reducing end acting exoglucanase (CBH I) from T. reesei; GH7; CBM1
- Non-reducing end acting (CBH II); GH6; CBM1
