General annotation (Comments)

Function

Hydrolyzes pullulan, a linear polymer which is composed of maltotriose units with alpha-1,6 glucosidic linkages, to produce isopanose (Glca1-4Glca1-6Glc).

Catalytic activity

Hydrolysis of pullulan to isopanose (6-alpha-maltosylglucose).

Subcellular location

Secreted.

Post-translational modification

N-glycosylated.
