Clostridium fervidus is a thermophilic, anaerobic bacterium which uses solely Na+ as a coupling ion for energy transduction. Important features of the primary Na+ pump (ATPase) that generates the sodium motive force are presented. The advantage of using a sodium rather than a proton motive force at high temperatures becomes apparent from the effect of temperature on H+ and Na+ permeation in liposomes.
嗜热梭菌是一种嗜热厌氧菌,它仅将Na⁺作为能量转导的偶联离子。本文介绍了产生钠动力势的初级Na⁺泵(ATP酶)的重要特性。从温度对脂质体中H⁺和Na⁺渗透的影响可以看出,在高温下使用钠动力势而非质子动力势的优势。
