    • The present invention relates to a chemically modified mutant protein including a cysteine residue substituted for a residue other than cysteine n a precursor protein, the substituted cysteine residue being subsequently modified by reacting the cysteine residue with a glycosylated thiosulfonate. Also a method of producing the chemically modified mutant protein is provided. The present invention also relates to a glycosylated methanethiosulfonate. Another aspect of the present invention is a method of modifying the functional characteristics of a protein including providing a protein and reacting the protein with a glycosylated methanethiosulfonate reagent under conditions effective to produce a glycoprotein with altered functional characteristics as compared to the protein. In addition, the present invention relates to methods of determining the structure-function relationships of chemically modified mutant proteins. The present invention also relates to synthetic methods for producing thio-glycoses, the thio-glycoses so produced, and to methods for producing glycodendrimer reagents.
    • 本发明涉及化学修饰的突变蛋白质,其包含半胱氨酸残基取代除半胱氨酸之外的残基前体蛋白质,随后通过使半胱氨酸残基与糖基化硫代磺酸盐反应来修饰取代的半胱氨酸残基。 还提供了生产化学修饰的突变蛋白的方法。 本发明还涉及糖基化的甲硫代磺酸盐。 本发明的另一个方面是改变蛋白质的功能特征的方法,包括提供蛋白质并且使蛋白质与糖基化甲硫代磺酸盐试剂在有效产生与蛋白质相比具有改变的功能特性的糖蛋白的条件下反应。 另外,本发明涉及确定化学修饰的突变蛋白的结构 - 功能关系的方法。 本发明还涉及用于产生硫代糖的合成方法,由此产生的硫代糖,并且涉及用于生产糖代码二聚体试剂的方法。
