Figure 3.
The left two columns show the normalized fs-resolved fluorescence transients of Y12W from seven selected wavelengths in the apo state on the short and long time ranges. The middle two columns are the corresponding normalized fs-resolved fluorescence transients of Y12W in the binary state with binding of DNA. The last column shows the normalized fs-resolved fluorescence transients of DNA alone in buffer solution. All the experimental data are shown in circles and the solid lines are the best exponential fit.
