Unit Definition: One unit will produce a ΔA800 of 0.001 per minute at pH 7.5 and 25°C, using a suspension of brewers yeast as a substrate in a 3 mL reaction mixture.

This enzyme catalyzes the lysis of yeast cells and hydrolyzes glucose polymers with β-1,3-linkages (e.g., glucan). It is also useful for preparing yeast spheroplasts.
