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.
We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Greener Chemistry. This product has been enhanced for energy efficiency. Find details here.

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.

Unit Definition

Unit Definition: A unit will turn over 1 nmole of methyl-umbelliferyl beta-D cellobioside per min at pH 5 at 50° C.

Physical form

Provided as an ammonium sulfate precipitate with the source as recombinant maize.

Plant cell-wall polysaccharides represent a vast source of food in nature. To depolymerize polysaccharides to soluble sugars, many organisms use multifunctional enzyme mixtures consisting of glycoside hydrolases, lytic polysaccharide mono-oxygenases, polysaccharide lyases, and carbohydrate esterases, as well as accessory, redox-active
