Application

Application Comment Organism
synthesis combination of maltogenic amylase reactions from Bacillus stearothermophilus and 4-alpha-glucanotransferase from Thermus scotoductus to increase the water solubility of puerarin, an isoflavonoid derived from Radix puerariae. The puerarin transfer products, including maltosyl-alpha-(1->6)-puerarin as a major product, are reacted with alpha-glucanotransferase in the presence of amylose. The maltosyl-alpha-(1->6)-puerarin-cycloamylose complex is formed by an elongation reaction and cyclization by alpha-glucanotransferase. The encapsulation of puerarin or glycosylated puerarin with a macrocyclic amylose is widely applicable both to improving the water solubility of the compound and stabilizing it during cold storage Thermus scotoductus
