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]

Accessibility

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

Mixed

Processivity

Synergism

1. Error fetching PMID 7980450: [Synergism1]

Substrates

Crystalline cellulose

Non-crystalline cellulose

etc.
