Long Time

Protein-DNA interactions are the core of the cell’s molecular machinery. For a long time, conventional biochemical methods served as a powerful investigatory basis of protein-DNA interactions and target search mechanisms. Currently single-molecule (SM) techniques have emerged as a complementary tool for studying these interactions and have revealed plenty of previously obscured mechanistic details. In comparison to the traditional ones, SM methods allow direct monitoring of individual biomolecules. Therefore, SM methods reveal reactions that are otherwise hidden by the ensemble averaging observed in conventional bulk-type methods. SM biophysical techniques employing various nanobiotechnology methods for immobilization of studied molecules grant the possibility to monitor individual reaction trajectories of biomolecules. Next-generation in vitro SM biophysics approaches enabling high-throughput studies are characterized by much greater complexity than the ones developed previously. Currently, several high-throughput DNA flow-stretch assays have been published and have shown many benefits for mechanistic target search studies of various DNA-binding proteins, such as CRISPR-Cas, Argonaute, various ATP-fueled helicases and translocases, and others. This review focuses on SM techniques employing surface-immobilized and relatively long DNA molecules for studying protein-DNA interaction mechanisms.

AbstractIn this work, we combine nanoscale engineering with single-molecule biology to probe the biochemical interactions between individual proteins and DNA. This approach, a vast improvement over previous methods, constructs a platform to observe thousands of protein-DNA interactions in real time with unprecedented detail. A key challenge in these experiments involves collecting enough statistically relevant data in order to analyze reactions which are designed to be probed individually. “DNA curtains” are formed by flowing the DNA tethered to a lipid bilayer across nanopatterned barriers, facilitating massively parallel data acquisition.
