What is the substrate and product of cellulase?
What is the substrate and product of cellulase?
Cellulases play a predominant role in the hydrolysis of cellulosic substrates and their conversion into monomeric products. They hydrolyse the β-1,4-glycosidic linkages of cellulose, and are synthesized by microbial strains during their growth on cellulosic materials.
What is the substrate of cellulase enzyme?
Cellulose, the substrate of cellulase, is the most abundant polysaccharide present on earth.
What is the product of cellulose cleavage by cellulase?
After the first cleavage, cellobiose will be the only product, as all the enzyme-bound ends have the same stereochemistry after the first cleavage. Thus, more processive enzymes will produce a higher ratio of cellobiose to cellotriose.
What does cellulase break cellulose into?
Cellulase enzymes are used to break down the cellulose of plant cell walls into simple sugars that can be transformed (fermented) by microbes to fuels, primarily ethanol, as well as to chemicals, plastics, fibers, detergents, pharmaceuticals, and many other products.
What is the structure of cellulase?

Which fungus is responsible for Biodeterioration of cellulose?
The ability to degrade plant biomass and cellulose as its major component is widespread in fungi. Trichoderma reesei is a mesophilic soft-rot fungus that is extensively used as a source of cellulases and hemicellulases for various applications.
How is cellulase secreted?
Cellulase plays a mainly catalytic role in the extracellular matrix where the enzymatic reaction takes place [8,9]. Therefore, cellulases are produced from cells through a certain pathway, which may not be limited to the secretion of a single enzyme, but a group of proteins.
What substrates can be used for cellulase reaction?
1 Department of Chemical Engineering, Auburn University, Alabama 36849, USA. Cellulase reaction mechanism was investigated with the use of following pure cellulosic substrates: Microcrystalline cellulose (Avicel), alpha-cellulose (Sigma), filter paper, cotton, and non-crystalline cellulose (NCC).
What is a cellulase enzyme?
Cellulase is any of several enzymes produced chiefly by fungi, bacteria, and protozoans that catalyze cellulolysis, the decomposition of cellulose and of some related polysaccharides. The name is also used for any naturally occurring mixture or complex of various such enzymes, that act serially or synergistically to decompose cellulosic material.
Can cellulase II degrade carboxymethyl-cellulose?
Cellulase II cannot degrade carboxymethyl-cellulose, and with filter paper as substrate the end product was cellobiose, which indicates that cellulase II is an exo-beta-1,4-glucan cellobiosylhydrolase.
What is the mechanism of action of inducible cellulase?
Cellulases are inducible enzymes and the regulation of the cellulase production is finely controlled by activation and repression mechanism. The production of cellulolytic enzyme is induced only in presence of the substrate, and is repressed when easily utilizable sugars are available.
