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).

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

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

Unusual kinetic behaviour was observed in assaying spectrophotometrically for exo-glucanase activity in a beta-glucosidase isolated from A. faecalis using p-nitrophenyl beta-cellobioside as substrate. At high substrate concentrations no phenol was released whereas at low concentrations a rapid release of phenol

An exo-beta-1,4-glucanase (Exo A) from Ruminococcus flavefaciens FD-1 was purified to homogeneity and characterized. Enzyme activity was monitored during purification by using the substrate p-nitrophenyl-beta-D-cellobioside (NPC). Over 85% of the NPC activity was found to be extracellular once the filter
