Through this method we have discovered that UvrA interacts with DNA in two phases; a slow phase (~1.3/s) that correlates with an ATP-consuming state previously identified, and a second, much faster search mode. These faster interactions persist for ~130 ms and using ATP analogues we determine this phase does not require ATP consumption.
