General annotation (Comments)

Function

May provide a degree of protection against microbial invasion of germinated barley grain through its ability to degrade fungal cell wall polysaccharides.

Catalytic activity

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

Subcellular location

Vacuole Probable.

Tissue specificity

Aleurone layer of germinated grain.

Sequence similarities

Belongs to the glycosyl hydrolase 17 family.
