to a protein scaffold is an attractive approach to the construction of artificial metalloenzymes since this is conveniently achieved by self-assembly. Here, we report a novel design for supramolecular artificial metalloenzymes that exploits the promiscuity of the central hydrophobic cavity of the transcription factor Lactococcal multidrug resistance Regulator (LmrR) as a generic binding site for planar
过渡金属复合物与蛋白质支架的超分子锚定是构建人工金属酶的一种有吸引力的方法,因为这可以通过自组装方便地实现。在这里,我们报告了一种超分子人工金属酶的新设计,它利用转录因子乳球菌多药耐药调节因子 (LmrR) 的中央疏水腔的混杂性作为不提供特定蛋白质结合相互作用的平面配位复合物的通用结合位点。这种方法的成功体现在 Cu(II) 催化的吲哚的对映选择性 Friedel-Crafts 烷基化中实现的优异对映选择性。
