Abstract
The rate of [(14)C]lactose inflow into anaerobic, non-metabolizing, Escherichia coli has been correlated with the rate of the simultaneous effective inflow of H(+). It is shown that the initial rates of the two transport processes are essentially the same, and it is concluded that the two processes are strictly coupled with a 1:1 stoicheiometry.
摘要
[(14)C]乳糖流入厌氧、不进行代谢的大肠杆菌的速率已与同时发生的H⁺有效流入速率相关联。结果表明，这两个转运过程的初始速率基本相同，并且得出结论，这两个过程以1:1的化学计量比严格偶联。
