CC -!- FUNCTION: Has endoglucanase activity on substrates containing beta-1,4
CC glycosidic bonds, like in carboxymethylcellulose (CMC),
CC hydroxyethylcellulose (HEC) and beta-glucan. Involved in the
CC degradation of complex natural cellulosic substrates (By similarity).
CC {ECO:0000250}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=Endohydrolysis of (1->4)-beta-D-glucosidic linkages in
CC cellulose, lichenin and cereal beta-D-glucans.; EC=3.2.1.4;
CC -!- SUBCELLULAR LOCATION: Secreted {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the glycosyl hydrolase 5 (cellulase A) family.
CC {ECO:0000305}.
