Protein attributes

Sequence length	654 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is further processed into a mature form.
Protein existence	Inferred from homology

General annotation (Comments)

Function	Exhibits both beta-glucosidase and beta-xylosidase activities.
Catalytic activity	Hydrolysis of terminal, non-reducing beta-D-glucosyl residues with release of beta-D-glucose. Hydrolysis of (1->4)-beta-D-xylans, to remove successive D-xylose residues from the non-reducing termini.
Subcellular location	Periplasm.
Sequence similarities	Belongs to the glycosyl hydrolase 3 family.
