We report here the use of an intein-mediated protein ligation strategy for the synthesis of glycoproteins and proteins containing various molecular probes. Several simple cysteine derivatives are synthesized and used as nucleophiles for specific incorporation onto the C-terminus of proteins expressed as N-terminal intein fusions. Examples of C-terminal carbohydrate labeling, fluorescence labeling,
我们在这里报告了使用内含肽介导的蛋白质连接策略来合成含有各种分子探针的糖蛋白和蛋白质。几种简单的半胱氨酸衍生物被合成并用作亲核试剂,用于特异性掺入表达为 N 端内含肽融合蛋白的蛋白质的 C 端。介绍了 C 端碳水化合物标记、荧光标记、金属螯合剂的掺入和核苷酸的掺入的例子。
