Figure 3FRET histogram of all binding events from the construct containing a single PAM next to the partial target. Y axis represents total number of counts.Example FRET traces from single-target multiple-PAM experiments. Top trace shows an example of a single-step binding event and a binding event that starts at a lower FRET state before transitioning to productive binding high-FRET state. Bottom trace shows an example of FRET fluctuations between the high-FRET state and lower FRET states.A histogram showing the percentage of dynamic. The percentage values were obtained from five experiments on five different days. Error bars represent standard error of the mean. The percentage of events showing dynamic binding behavior was calculated by dividing the number of binding events that showed such behavior by the total number of binding events.A scatter plot showing the time Cas9 spends in a lower FRET state before transitioning to a high-FRET state. The dwelltimes increase with the number of PAMs adjacent to the target. Such dwelltime could not be determined for a construct containing a single PAM. The values were obtained from five experiments on five different days. Error bars represent standard error of the mean.
Figure 4Example fluorescence traces showing Cas9 transitioning between H and L targets with increasing target distances (right). FRET histograms constructed from events that show fluctuations showing two FRET peaks corresponding to binding to either target. High FRET peak stays the same in each histogram, but lower FRET peak moves to lower FRET values as the distance between targets increases.A scatter plot showing the probability of Cas9 transitioning between targets before dissociation. The values are averages from five measurements and error bars represent standard error of the mean. The transition probability (p = T / (T+D)) was calculated by summing up all the number of FRET transitions (T) and dividing T by the sum of T and the total number of dissociation events (D).A histogram showing all dwelltimes from single-target controls and tandem-target experiments. τ1 is similar for single-target control and tandem target experiments. τ2 only appears in tandem target experiments and is over 20-fold higher than τ1 or τst. The values represent the mean dwelltimes that were obtained by fitting dwelltime distributions by either single or double exponential decay function from five measurements. Error bars represent standard error of the mean.

Binding rate decreases moderately with increasing number of adjacent PAMs. The values are averages of four measurements over three days. Error bars represent standard error of the mean. kon-target was calculated using the equation kon-target=1/ (CxΔτon) where C is the molarity of DNA target in the channel.
