Application

Isoamylase from Pseudomonas sp. has been used in starch debranching[1] and to measure the chain-length distributions.[2]

Biochem/physiol Actions

Catalyzes the hydrolysis of (1-6)-α-D-glucosidic branch linkages in glycogen, amylopectin and their β-limit dextrins.
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.

Analysis Note

≥10 MU/mg protein

Other Notes

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)

Finding an efficient and eco-friendly solution for starch dissolution has attracted considerable attentions in recent years. This study investigated the structural characteristics, and degradation behavior of corn starch in KOH/thiourea aqueous solution by the comparison with DMSO/LiBr and 1-allyl-3-methylimidazolium chloride

Several studies have suggested that debranching enzymes (DBEs) are involved in the biosynthesis of amylopectin, the major constituent of starch granules. Our systematic analysis of all DBE mutants of Arabidopsis thaliana demonstrates that when any DBE activity remains, starch granules

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)
