| Application: | Cellobiohydrolase I can be used in combination with endocellulases and b-glucosidase to produce glucose from cellulose. |
| Biochem/physiol Actions: | Cellobiohydrolase (CBH) is a cellulase which degrades cellulose by hydrolysing the 1,4-β-D-glycosidic bonds. CBH is an exocellulase which cleaves two to four units from the ends of cellulose. CBH I cleaves progressively from the reducing end. CBH I is commonly used in detergents for cleaning textiles. Its ezymatic activity ranges from 37° C to 50° C, with its optimal temperature being approximately 45° C. The optimum pH for the enzyme is 5-6. |
| General description: | Cellubiohydrolase I is an enzyme present in many fungi, but particularly wood rot fungi. It is a monomer of 53 kDa with a catalytic domain and a cellulose binding domain. The reaction adds water to the glucose bonds in cellulose (non-reducing ends of the chain), yielding cellobiose. |
