Photo-physical properties of mNeonGreen and Dronpa. Histogram of detected photon number for (a) mNeonGreen or Dronpa fused to DivIVA expressing B. subtilis strains (BHF039) or Dronpa (BHF057), respectively. Mean and median of the number of photons are indicated. (b, left) Initial linear section of the relative cumulative on-switching probability vs time was fitted (red dotted line) linearly to obtain the on-switching rate. (b, right) Distribution of the on-state lifetime was fitted to an exponential decay function (red dotted line) to obtain the mean life time, the inverse of which yields the off-switching rate. One frame corresponds to 20 ms. (See also Supplementary Table I).
