  This article reports on the extraction behavior of heme proteins from an aqueous phase into ionic liquids (ILs) with dicyclohexano-18-crown-6 (DCH18C6), and the structure−function relationship of cytochrome c (Cyt-c) dissolved in ILs. We have found that DCH18C6 enables transfer of Lys-rich proteins into ILs via supramolecular complexation. The hydrophobicity and functional groups of ILs have a great influence on protein partitioning, and a hydroxyl group-containing IL with DCH18C6 is capable of the quantitative partitioning of Cyt-c. On the other hand, protein transfer using conventional organic solvents is negligibly small. UV−visible, CD, and resonance Raman spectroscopic characterizations indicate that the sixth ligand Met 80 in the heme group of the Cyt-c−DCH18C6 complex in IL is replaced by other amino acid residues of the peptide chain and that a non-natural, six-coordinate, low-spin ferric heme structure is induced in IL. Solubilization of Cyt-c in IL causes the environmental change of the heme vicinity of Cyt-c, which triggers the functional conversion of Cyt-c from an electron-transfer protein to peroxidase. The Cyt-c−DCH18C6 complex in IL provides remarkably high peroxidase activity compared with native Cyt-c, because of enhancement of the affinity for H2O2.

  本文报告了用二环己烷-18-冠醚-6（DCH18C6）将血红素蛋白从水相萃取到离子液体（ILs）中的行为，以及溶解在离子液体中的细胞色素 c（Cyt-c）的结构-功能关系。我们发现，DCH18C6 可使富含 Lys 的蛋白质通过超分子复合物转移到 IL 中。IL的疏水性和官能团对蛋白质的分配有很大影响，含有DCH18C6的含羟基IL能够定量分配Cyt-c。另一方面，使用传统有机溶剂的蛋白质转移量微乎其微。紫外-可见光、CD 和共振拉曼光谱表征表明，IL 中 Cyt-c-DCH18C6 复合物血红素基团中的第六配体 Met 80 被肽链的其他氨基酸残基取代，IL 中诱导出一种非天然、六配位、低自旋铁血黄素结构。Cyt-c 在 IL 中的溶解会导致 Cyt-c 附近的血红素发生环境变化，从而引发 Cyt-c 从电子转移蛋白向过氧化物酶的功能转换。与原生 Cyt-c 相比，IL 中的 Cyt-c-DCH18C6 复合物具有极高的过氧化物酶活性，这是因为它对 H2O2 的亲和力增强了。

  Imidazolium cations, such as those commonly used in preparing ionic liquids (ILs) can easily be derivatized to include task-specific functionality, such as metal ligating groups that when used as part of the solvent or doped into less expensive ILs, dramatically enhance the partitioning of targeted metal ions into the IL phase from water; the strategy of preparing task-specific ILs is applicable to a wide range of designer solvent needs.

  咪唑阳离子，如制备离子液体（IL）时常用的咪唑阳离子，可以很容易地衍生出针对特定任务的功能，如金属配位基团，当这些金属配位基团作为溶剂的一部分使用或掺杂到价格较低的离子液体中时，可以显著提高目标金属离子从水中分离到离子液体相中的能力；制备针对特定任务的离子液体的策略适用于各种设计溶剂的需求。
