These substrates can be subdivided into two classes- Insoluble chromogenic substrates: An insoluble cellulase substrate such as AZCL-HE-cellulose absorbs water to create gelatinous particles when placed in solution. This substrate is gradually depolymerised and solubilised by the action of cellulase.
Cellulose microfibrils are made on the surface of cell membranes to reinforce cells walls, which has been researched extensively by plant biochemists and cell biologist because 1) they regulate cellular morphogenesis and 2) they serve alongside many other constituents (i.e. lignin, hemicellulose, pectin) in the cell wall as a strong structural support and cell shape.

Moreover, CMC has been used extensively to characterize enzyme activity from endoglucanases (part of the cellulase complex); it is a highly specific substrate for endo-acting cellulases, as its structure has been engineered to decrystallize cellulose and create amorphous sites that are ideal for endoglucanase action.
Some termites contain in their hindguts certain flagellate protozoa producing such enzymes, whereas others contain bacteria or may produce cellulase. [40] The enzymes used to cleave the glycosidic linkage in cellulose are glycoside hydrolases including endo-acting cellulases and exo-acting glucosidases.
CodeXyme® 3 (Codexis' cellulase enzyme from 2011) was found to convert the same or more glucan at the same enzyme load as competing cellulase packages, and CodeXyme® 4 fared even better against ...
Attachment of the cellulosome to its substrate is mediated by a scaffoldin-borne cellulose-binding module (CBM) that comprises part of the scaffoldin subunit. Much of our understanding of its catalytic components, architecture, and mechanisms of attachment to the bacterial cell and to cellulose, has been derived from the study of Clostridium ...
The global production of CA materials was over 800,000 tonnes (790,000 long tons; 880,000 short tons) per year in 2008. While it was initially believed that CA was virtually non-biodegradable, it has been shown that after initial partial deacetylation, the polymer's cellulose backbone is readily biodegraded by cellulase enzymes.
A cellulase unit (CU) is a unit of measurement for the enzyme cellulase.One cellulase unit is that activity that will produce a relative fluidity change of one in 5 minutes in a defined carboxymethylcellulose substrate under the conditions of an assay (50 deg Celsius, pH 4.5). [1]
