Speed Switching of Gonococcal Surface Motility Correlates with Proton Motive Force
Figure 2
Components of the proton motive force of N. gonorrhoeae.
(a) Intracellular pH (pHin) and (b) ΔpH-component of the PMF versus extracellular pH (pHex). black: cFDA-SE (N = 100-1000 cells per data point), red: single cell analysis of pHluorin expressing cells (N = 240-530 cells per data point), green spectroscopic analysis of of pHluorin expressing cells (3 independent experiments). Full line in (a): pHin = pHex. (c) Transmembrane potential ΔΨ as a function of pHex (N = 100-200 cells per data point).
