CC -!- FUNCTION: Glucanases play a role in cell expansion during growth, in
CC cell-cell fusion during mating, and in spore release during
CC sporulation. This enzyme may be involved in beta-glucan degradation.
CC Active on laminarin and lichenan (By similarity). {ECO:0000250}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=Hydrolysis of (1->3)-beta-D-glucosidic linkages in (1->3)-
CC beta-D-glucans.; EC=3.2.1.39;
CC -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000250}; Single-pass type II
CC membrane protein {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the glycosyl hydrolase 17 family. {ECO:0000305}.
