Comparative kinetic analysis of two fungal β-glucosidases

Abstract

This article provides a useful comparison between the activity of beta-glucosidases from two different fungi, and shows the importance of fully characterizing both enzymes. A Michaelis-Menten model was developed, including glucose inhibition and kinetic parameters, which were accurately determined and compared. This model can be further integrated into a cellulose hydrolysis model dissociating beta-glucosidase activity from that of other cellulases. It can also help to define the optimal enzymatic cocktails for new beta-glucosidase activities.
