Application

4-Nitrophenyl β-D-cellobioside has been used as a substrate to assay β-D-celluliosidase or cellobiohydrolase (exocellulase) activity in the microbial community. It has also been used as a substrate to study the endoglucanase J30 activity.

Biochem/physiol Actions

4-Nitrophenyl β-D-cellobioside is a cellotriose analog, and a chromogenic substrate commonly used for the detection of cellulase activity. Exoglucanase, endoglucanase and β -glucosidase hydrolyze 4-nitrophenyl β-D-cellobioside to form p-nitrophenol (PNP).

The p-nitrophenylcellobiosidase (PNPCase) activity of Trichoderma reesei cellobiohydrolase I (CBH I) was competitively inhibited by concentrations of guanidine hydrochloride (Gdn HCl) that did not affect the tryptophan fluorescence of this enzyme. The Km of CBH I, 3.6 mM, was increased

Conformational changes to 1,4-beta-D-glucan cellobiohydrolase I (CBHI) in response to its binding with p-nitrophenyl beta-D-cellobioside (PNPC) were analyzed by second-derivative fluorescence spectrometry at the saturation binding point. Irreversible changes to the configuration of PNPC during the course of the binding

An enzyme active against p-nitrophenyl-beta-D-glucoside was purified from logarithmic-phase cells of Ruminococcus albus cultivated in a medium containing ball-milled cellulose. The purification yielded homogeneous enzyme after an approximately 520-fold increase in specific activity and a 9% yield. The enzyme was
