analogues of the [FeFe]-hydrogenase in designed peptides via on resin modification of an amino acid side chain with a dithiol functional group is described. Utilizing a unique amine side chain as anchor, the dithiol unit is coupled to the peptide via formation of an amide. This dithiol unit precisely positions the two required sulfur atoms for the formation of a [(μ-SRS)Fe(CO)3}2] cluster on reaction with
描述了通过树脂修饰具有二硫醇官能团的氨基酸侧链将 [FeFe]-氢化酶的合成类似物固定在设计的肽中的一般方法。利用独特的胺侧链作为锚,二硫醇单元通过形成酰胺与肽偶联。该二硫醇单元精确定位了在与 [Fe3(CO)12] 反应时形成 [(μ-SRS)Fe(CO)3}2] 簇所需的两个硫原子。UV/Vis 和 FTIR 光谱证明了所需复合物的形成。
