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 7 (cellulase C) family.
CC       {ECO:0000305}.
