애플리케이션

Isoamylase from Pseudomonas sp. has been used in starch debranching and to measure the chain-length distributions.

생화학적/생리학적 작용

Pseudomonas amyloderamosa is considered a popular source of isoamylase. In the presence of a surfactant, this isoamylase produces a series of maltooligosaccharides. Immobilized isoamylase makes it applicable with a polysaccharide matrix composed of agarose, cellulose, and raw corn starch.
Catalyzes the hydrolysis of (1-6)-α-D-glucosidic branch linkages in glycogen, amylopectin and their β-limit dextrins.

단위 정의

One unit causes an increase in A610 of 0.1 in 1 hour using a homogenized solution of rice starch as a substrate (pH 3.5, 40°C)

Glycogen, highly branched (1-->4)(1-->6)-linked alpha-d-glucan, can be extracted from natural sources such as animal tissues or shellfish (natural source glycogen, NSG). Glycogen can also be synthesized in vitro from glucose-1-phosphate using the cooperative action of alpha-glucan phosphorylase (GP, EC 2.4.1.1)
