Unit definition:
One Unit of exo-1,3-β-glucanase activity is defined as the amount of enzyme required to release one μmole of glucose reducing-sugar equivalents per minute from laminarin (10 mg/mL) in sodium acetate buffer (100 mM), pH 4.0 at 40^oC.

One Unit of β-glucosidase activity is defined as the amount of enzyme required to release one μmole of p-nitrophenol per minute from 4-nitrophenyl-β-D-glucpyranoside in sodium acetate buffer (100 mM), pH 4.0 at 40^oC.

Specificity:
exo-1,3-β-glucanase: Successive hydrolysis of β-D-glucose units from the non-reducing ends of (1,3)-β-D-glucans, releasing α-glucose.

β-glucosidase: Hydrolysis of terminal, non-reducing β-D-glucosyl residues with release of β-D-glucose.

Applications:
For use in the determination of (1,3)(1,4) β-glucan.
