General annotation (Comments)

Function

Has endoglucanase activity on substrates containing beta-1,4 glycosidic bonds, like in carboxymethylcellulose (CMC), hydroxyethylcellulose (HEC) and beta-glucan. Involved in the degradation of complex natural cellulosic substrates By similarity.

Catalytic activity

Endohydrolysis of (1->4)-beta-D-glucosidic linkages in cellulose, lichenin and cereal beta-D-glucans.

Subcellular location

Secreted By similarity.

Sequence similarities

Belongs to the glycosyl hydrolase 5 (cellulase A) family.
