CC -!- FUNCTION: Beta-glucanases participate in the metabolism of beta-glucan,
CC the main structural component of the cell wall. Acts on lutean,
CC pustulan and 1,6-oligo-beta-D-glucosides (By similarity).
CC {ECO:0000250}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=Random hydrolysis of (1->6)-linkages in (1->6)-beta-D-
CC glucans.; EC=3.2.1.75;
CC -!- SUBCELLULAR LOCATION: Secreted {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the glycosyl hydrolase 5 (cellulase A) family.
CC {ECO:0000305}.
