Protein attributes

Sequence length	814 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is further processed into a mature form.
Protein existence	Evidence at protein level.

General annotation (Comments)

Function	This enzyme catalyzes the endohydrolysis of 1,4-beta-glucosidic linkages in cellulose, lichenin and cereal beta-D-glucans.
Catalytic activity	Endohydrolysis of (1->4)-beta-D-glucosidic linkages in cellulose, lichenin and cereal beta-D-glucans.
Domain	A 24 residues domain is repeated twice in this enzyme as well as in other C.thermocellum cellulosome enzymes. This domain may function as the binding ligand for the SL component.
Sequence similarities	Belongs to the glycosyl hydrolase 5 (cellulase A) family.
