sensitive or insensitive to differences in enzyme or substrate concentration. Here, we report the first supramolecular system where the catalytic activity is made concentration independent through the use of newly designed inhibitor molecules. The precise concentration dependence of coupled supramolecular equilibriums between free catalyst, inhibited catalyst, active inhibitor, and inactive inhibitor allows
生物系统中的酶活性通常受控制机制的控制,其中催化特性对酶或底物浓度的差异敏感或不敏感。在这里,我们报告了第一个超分子系统,其中通过使用新设计的抑制剂分子使催化活性与浓度无关。游离催化剂、抑制催化剂、活性抑制剂和非活性抑制剂之间耦合超分子平衡的精确浓度依赖性允许将游离催化剂的浓度保持在 1 mM 的宽浓度范围内,从而产生自动调节的催化系统。
