Protein attributes
| Sequence length | 714 AA. |
| Sequence status | Complete. |
| Sequence processing | The displayed sequence is further processed into a mature form. |
| Protein existence | Inferred from homology |
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 By similarity. |
| 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. |
