AbstractS‐adenosylmethionine‐dependent methyltransferases are involved in countless biological processes, including signal transduction, epigenetics, natural product biosynthesis, and detoxification. Only a handful of carboxylate methyltransferases have evolved to participate in amide bond formation. In this report we show that enzyme‐catalyzed F‐methylation of carboxylate substrates produces F‐methyl esters that readily react with N‐ or S‐nucleophiles under physiological conditions. We demonstrate the applicability of this approach to the synthesis of small amides, hydroxamates, and thioesters, as well as to site‐specific protein modification and native chemical ligation.
摘要依赖于腺苷蛋氨酸的甲基转移酶参与了无数生物过程,包括信号转导、表观遗传学、天然产物生物合成和解毒。只有少数羧酸甲基转移酶进化到参与酰胺键的形成。在本报告中,我们展示了酶催化羧酸底物的 F-甲基化产生的 F-甲基酯在生理条件下很容易与 N-或 S-亲核物发生反应。我们证明了这种方法适用于合成小酰胺、羟酰胺和硫代酯,以及蛋白质的特定位点修饰和原生化学连接。
