酶向细胞内膜的募集通常调节它们的催化活性,这在细胞信号传导和膜运输中可能是重要的。因此,重新定位不仅对这些酶获得其底物是重要的,而且膜相互作用通常通过在不同的时间和幅度尺度上诱导构象变化来变构调节酶功能。最近的结构,生物物理和计算研究揭示了关键酶如何与脂质膜表面相互作用,以及这种膜结合如何调节蛋白质的结构和功能。本文综述了酶与膜相互作用的调控机制的研究进展。
Recruitment of enzymes to intracellular membranes often modulates their catalytic activity, which can be important in cell signaling and membrane trafficking. Thus, re-localization is not only important for these enzymes to gain access to their substrates, but membrane interactions often allosterically regulate enzyme function by inducing conformational changes across different time and amplitude scales. Recent structural, biophysical and computational studies have revealed how key enzymes interact with lipid membrane surfaces, and how this membrane binding regulates protein structure and function. This review summarizes the recent progress in understanding regulatory mechanisms involved in enzyme-membrane interactions.
