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-+¦-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.
Physical form: Enzyme is provided in a sodium acetate and ammonium sulfate solution, containing 0.02% sodium azide.
Unit Definition: One unit will turn over 1 mumole MUC per min at pH 5 at 50 C.
