Biochem/physiol Actions
β-glucanases degrade β-1,4-glucans of cellulose, xyloglucan and β-1,4-xylan.
Unit Definition
One unit corresponds to the amount of enzyme which will release 1 μmole of reducing sugar equivalents (expressed as glucose) per minute at pH 5.0 and 55 °C, using β-D-glucan (Cat. No. 49102) as substrate

In vitro evolution methods are often used to modify protein with improved characteristics. We developed a directed evolution protocol to enhance the thermostability of the beta-1,3-1,4-glucanase. The thermostability of the enzyme was significantly improved after two rounds of directed evolution.
