Methionine chemical ligation is based on a convenient direct thioester formation at the C-terminus of the ligation site, on homocysteine reduction with dithiothreitol in order to liberate the mercapto group of the homocysteine residue at the N-terminus, and on chemoselective S-methylation with methyl iodide.
蛋氨酸化学连接的基础是:在连接位点的 C 端直接形成方便的硫代酯;用二硫苏糖醇还原同型半胱氨酸,以释放 N 端同型半胱氨酸残基的巯基;以及用甲基碘进行化学选择性 S 甲基化。
