Sequence statusComplete.
Sequence processingThe displayed sequence is further processed into a mature form.
Protein existenceEvidence at protein level.

General annotation (Comments)

Catalytic activity

Cyclizes part of a (1->4)-alpha-D-glucan chain by formation of a (1->4)-alpha-D-glucosidic bond.

Cofactor

Binds 2 calcium ions per subunit.

Subunit structure

Monomer.

Subcellular location

Secreted By similarity.

Domain

May consist of two protein domains: the one in the N-terminal side cleaves the alpha-1,4-glucosidic bond in starch, and the other in the C-terminal side catalyzes other activities, including the reconstitution of an alpha-1,4-glucosidic linkage for cyclizing the maltooligosaccharide produced.

Sequence similarities

Belongs to the glycosyl hydrolase 13 family.

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

Contains 1 IPT/TIG domain.
