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.

Domain

Has a modular structure: an endo-beta-1,4-glucanase catalytic module at the N-terminus, a linker rich in serines and threonines, and a C-terminal carbohydrate-binding module (CBM). The genes for catalytic modules and CBMs seem to have evolved separately and have been linked by gene fusion.

Sequence similarities

Belongs to the glycosyl hydrolase 61 family.

Contains 1 CBM1 (fungal-type carbohydrate-binding) domain.
