Characterization and Properties of Different Glucosyltransferases Isolated from Suspension-Cultured Cells of Daucus carota

Particulate enzymes (14,000 g pellet) from suspension-cultured carrot cells (Daucus carota L .) incorporated glucose from UDP-glucose and G DP-glucose into ethanol-insoluble products which were characterized as glucans or glucoprotein. Based on the test system to assay glucansynthetases I and II four different enzymatic activities could be distinguished on the basis o f their substrate and diva...
