Protein

Neopullulanase 2

Gene

tvaII

Organism
Thermoactinomyces vulgaris
Status
Reviewed - Annotation score: 4 out of 5- Experimental evidence at protein leveli

Functioni

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 activityi

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

Cofactori

Binds 1 calcium ion per subunit.
