  • Title: Transglucosylation activities of multiple forms of alpha-glucosidase from spinach.
    Author: Sugimoto M, Furui S, Sasaki K, Suzuki Y.
    Journal: Biosci Biotechnol Biochem; 2003 May; 67(5):1160-3. PubMed ID: 12834301.
    Abstract:
    Transglucosylation activities of spinach alpha-glucosidase I and IV, which have different substrate specificity for hydrolyzing activity, were investigated. In a maltose mixture, alpha-glucosidase I, which has high activity toward not only maltooligosaccharides but also soluble starch and can hydrolyze isomaltose, produced maltotriose, isomaltose, and panose, and alpha-glucosidase IV, which has high activity toward maltooligosaccharides but faint activity toward soluble starch and isomaltose, produced maltotriose, kojibiose, and 2,4-di-alpha-D-glucosyl-glucose. Transglucosylation to sucrose by alpha-glucosidase I and IV resulted in the production of theanderose and erlose, respectively, showing that spinach alpha-glucosidase I and IV are useful to synthesize the alpha-1,6-glucosylated and alpha-1,2- and 1,4-glucosylated products, respectively.
