    • An object of the present invention is to provide novel methods for forming glucosyl-transferred polyalcohols, glucosyl-transferred glucuronic acid, and glucosyl-transferred derivatives of glucose whose C-6 hydroxyl group bound to a saccharide by using an enzymatic reaction. The present invention solves the above object by providing a method for transferring a glucosyl residue to polyalcohols, glucuronic acid and/or derivatives of glucose whose C-6 hydroxyl group bound to a saccharide, comprising a step of: allowing a trehalose phosphorylase to act on a saccharide containing glucose as a component sugar and one or more polyalcohols selected from the group consisting of inositol, ribitol, erythritol, and glycerol; glucuronic acid and/or a salt thereof; and/or one or more derivatives of glucose whose C-6 hydroxyl group bound to a saccharide selected from the group consisting of isomaltose, gentiobiose, melibiose, isomaltotriose, and isopanose.
    • 本发明的目的是提供通过酶促反应形成C-6羟基与糖结合的葡萄糖转移的多元醇,葡糖基转移的葡萄糖醛酸和葡萄糖转移的葡萄糖转移衍生物的新方法。 本发明通过提供一种将葡糖基残基转移到多糖,葡糖醛酸和/或其C-6羟基与糖结合的葡萄糖的衍生物的方法,包括以下步骤:使海藻糖磷酸化酶作用于 含有葡萄糖作为组分糖和一种或多种选自肌醇,核糖醇,赤藓糖醇和甘油的多元醇的糖; 葡萄糖醛酸和/或其盐; 和/或一种或多种C-6羟基结合于选自异麦芽糖,龙胆糖,蜜二糖,异麦芽三糖和异丙糖的糖的葡萄糖衍生物。
