Application

4-Nitrophenyl β-D-lactopyranoside may be used as a substrate for determining β-lactosidase activity and for determining the substrate specificity for β-glucosidase from the yeast Debaryomyces hansenii.[1] It has also been used as a substrate for cellobiohydrolase.[2]

Understanding the pH effect of cellulolytic enzymes is of great technological importance. In this study, we have examined the influence of pH on activity and stability for central cellulases (Cel7A, Cel7B, Cel6A from Trichoderma reesei, and Cel7A from Rasamsonia emersonii).

Brainstem networks that control regular tidal breathing depend on excitatory drive, including from tonically active, CO2/H+-sensitive neurons of the retrotrapezoid nucleus (RTN). Here, we examine intrinsic ionic mechanisms underlying the metronomic firing activity characteristic of RTN neurons. In mouse brainstem
