Stoicheiometry of lactose-H+ symport across the plasma membrane of Escherichia coli.
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.
