Bioorthogonal covalent cross-linking of DNA-binding proteins (p53) to DNA was achieved through novel DNA probes bearing a reactive vinylsulfonamide (VS) group. The VS-modified dCTP served as building block for polymerase synthesis of modified DNA, which was readily conjugated with cysteine-containing peptides and proteins by Michael addition.
通过新型带有反应性乙烯砜酰胺(VS)基团的 DNA 探针,实现了 DNA 结合蛋白(p53)与 DNA 的生物正交共价交联。VS 修饰的 dCTP 可作为聚合酶合成修饰 DNA 的构建块,通过迈克尔加成反应,可将其与含有半胱氨酸的肽和蛋白质轻易地连接起来。
