Energy-transduction mechanisms in living organisms, such as photosynthesis and respiration, store light and chemical energy in the form of an electrochemical gradient created across a lipid bilayer. Herein we show that the proton concentration at an electrode/phospholipid-bilayer interface can be controlled and monitored electrochemically by immobilizing a membrane-bound hydrogenase. Thus, the energy derived from the electroenzymatic oxidation of H2 can be used to generate a proton gradient across the supported biomimetic membrane.
在生物体的能量传递机制中，例如光合作用和呼吸作用，将光能和化学能以跨脂质双层形成的电化学梯度的形式储存。在此，我们展示了通过固定膜结合氢化酶可以在电极/磷脂双层界面控制和电化学监测质子浓度。因此，来源于 H2 的电酶氧化的能量可以用于在支撑的仿生膜中产生质子梯度。
