The essential DNA helicase, PcrA, regulates recombination by displacing the recombinase RecA from the DNA. The nucleotide-bound state of RecA determines the stability of its nucleoprotein filaments. Using single-molecule fluorescence approaches, we demonstrate that RecA displacement by a translocating PcrA requires the ATPase activity of the recombinase. We(More)
Single molecule fluorescence microscopy can be used to follow the mechanics of molecular biology processes in real time. However, many factors, from flow cell preparation to improper data analysis can negatively impact single molecule fluorescence resonance energy transfer (smFRET) experiments. Here, we describe some best practices for ensuring that smFRET(More)
