General annotation (Comments)

Catalytic activity

Hydrolysis of terminal (1->4)-linked alpha-D-glucose residues successively from non-reducing ends of the chains with release of beta-D-glucose.

Sequence similarities

Belongs to the glycosyl hydrolase 15 family.

Contains 1 CBM20 (carbohydrate binding type-20) domain.

Alternative products

This entry describes 2 isoforms produced by alternative splicing. [Align] [Select]
Isoform G1 (identifier: P69328-1)
