debranching enzymes

de·branch·ing en·zymes

enzymes that bring about destruction of branches in glycogen; formerly considered to be one enzyme, now known to be a mixture of transferases (4-α-d-glucanotransferase) and hydrolases (amylo-1,6-glucosidase).

Hydrolysis of xylan (hemicellulose, second most abundant polymer in plant cell wall) is majorly catalyzed by xylanases followed by several other xylanolytic enzymes that includes a-d-xylosidase and a variety of debranching enzymes i.
Debranching enzymes removes all branching points in amylopectin, which results in an all-linear molecule with improved film-forming properties.
In the past, the metabolic role of debranching enzymes was initially thought to be the degradation of amylopectin in storage starch during germination, or in transitory starch.
2003) and Tetlow (2006) concluded that amylose content in cereal was mostly controlled by granule-bound starch synthase (GBSS), whereas amylopectin generally was synthesized by the coordinated actions of soluble starch synthases (SS), branching enzymes (BE), and debranching enzymes (DBE).
The starch- debranching enzymes isoamylase and pullulanase are both involved in amylopectin biosynthesis in rice endosperm.
