Protein attributes

Sequence length	762 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	Involved in mycoparasitism, hydrolyzes yeast and fungal cell walls. Classified as a small-oligosaccharide-producing type based its the end products: glucose, laminaribiose or laminaritetraose.
Catalytic activity	Hydrolysis of (1->3)-beta-D-glucosidic linkages in (1->3)-beta-D-glucans.
Enzyme regulation	Inhibited by glucose.
Subcellular location	Secreted.
Domain	The C-terminal cysteine-rich region may function as a fungal cell wall binding domain.
Post-translational modification	Does not seem to be glycosylated.
Sequence similarities	Belongs to the glycosyl hydrolase 55 family.
Biophysicochemical properties	Temperature dependence: Optimum temperature is 40 degrees Celsius. Inactive at 55 degrees Celsius.
