General annotation (Comments)

Function

Is thought to be an important plant defense-related product against fungal pathogens.

Catalytic activity

Hydrolysis of (1->3)-beta-D-glucosidic linkages in (1->3)-beta-D-glucans.

Subcellular location

Secreted › extracellular space Potential.

Tissue specificity

Accumulates in aleurone layers. Much lower levels are found in the embryo, and none in starchy endosperm.

Induction

By pathogen infection.

Sequence similarities

Belongs to the glycosyl hydrolase 17 family.
