Application

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

Biochem/physiol Actions

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.

Unit Definition

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)

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
