UniProt functional annotation for P43379

UniProt code: P43379.

Organism: Bacillus circulans.
Taxonomy: Bacteria; Firmicutes; Bacilli; Bacillales; Bacillaceae; Bacillus.
 
Catalytic activity: Cyclizes part of a (1->4)-alpha-D-glucan chain by formation of a (1->4)-alpha-D-glucosidic bond.
Cofactor: Binds 3 calcium ions per subunit.
Subunit: 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.
Similarity: Belongs to the glycosyl hydrolase 13 family.
Similarity: Contains 1 CBM20 (carbohydrate binding type-20) domain.
Similarity: Contains 1 IPT/TIG domain.
