  Peptide ligation assisted by an auxiliary attached to amidyl nitrogen

  摘要：

  New thiol-containing auxiliaries were developed for peptide ligation. They were placed at the amidyl N-atom in the second amino acid residue of a peptide fragment. With the new auxiliaries, peptide ligation could be conducted at non-Cys and non-Gly sites. Compared to other recently developed auxiliaries, an important feature of the present design was that the new auxiliaries were generally applicable and readily removable. (C) 2010 Elsevier Ltd.

  天然和蛋白酶抗性泛素化肽的简便合成

  摘要：

  双效泛素化：使用临时连接辅助剂 2-（氨基氧基）乙硫醇将泛素和 SUMO-3 位点特异性地连接到 Lys 侧链 ε-胺。还原后，连接产物是泛素 C 端水解酶 UCH-L3 和 SUMO 特异性蛋白酶 SENP1 的可行底物。泛素化肽中连接辅助剂的保留导致 UCH-L3 抗性类似物。

  has been developed as a building block for peptide ubiquitination, which is fully compatible with solid-phase Fmoc chemistry and common peptide modifications including phosphorylation, methylation, acetylation, biotinylation, and fluorescence labeling. The optimal conditions for peptide cleavage and auxiliary removal were obtained. The utility of this building block in peptide ubiquitination was demonstrated

  N -Boc- N -(2-(三苯甲基硫基)乙氧基)甘氨酸已被开发为肽泛素化的构建模块，它与固相 Fmoc 化学和常见的肽修饰完全兼容，包括磷酸化、甲基化、乙酰化、生物素化和荧光标记。获得了肽裂解和辅助去除的最佳条件。通过合成七种带有各种修饰的泛素化组蛋白和 Tau 肽，证明了该构建模块在肽泛素化中的实用性。 Cys 残基耐受性良好，不需要正交保护。通过荧光标记的泛素缀合物的酶促去泛素化证实了合成的泛素化肽的结构完整性和折叠。使用该构建模块的合成策略为制备具有多种修饰的泛素化肽提供了实用的方法。
