Starch branching enzyme (SBE) is crucial in the biosynthesis of starch, catalyzing the formation of α-1,6-glycosidic linkages in amylopectin, which increases the solubility and availability of starch for enzymatic digestion. The activity of SBE influences the structure and functionality of starch, impacting its industrial and nutritional applications.
