Enzymatic Synthesis of Carbohydrate Derivatives Using β-Glycosidase ofSulfolobus Solfataricus

Abstract

Enzymatic synthesis of different β-D-glycosides was obtained using as biocatalyst immobilized cells, crude homogenate, and homogeneous native and recombinat β-glycosidase activity of the thermophilic archaeon Sulfolobus solfataricus. In particular our investigation was concerned with the selectivity in the glycosylation of hydroxybenzyl alcohols, salicin, 1,2-propanediol, and more complex polyols as well as the use of immobilized cells for the synthesis of hexyl-β-D-glucoside. The aromatic glucosides obtained by enzyme-catalyzed transglucosylation were used for kinetic studies of purified Sulfolobus solfataricus enzyme in the hydrolysis reaction.
