General annotation (Comments)

Function

Hydrolyzes pullulan efficiently but only a small amount of starch. Endohydrolysis of 1,4-alpha-glucosidic linkages in pullulan to form panose. Cleaves also (1-6)-alpha-glucosidic linkages to form maltotriose.

Catalytic activity

Hydrolysis of pullulan to panose (6-alpha-D-glucosylmaltose).

Cofactor

Binds 1 calcium ion per subunit.

Subunit structure

Monomer.

Sequence similarities

Belongs to the glycosyl hydrolase 13 family.
